Sir you make organic chemistry possible and easy to understand otherwise it seems not possible to understand it sir jazakAllah thanks a lot sir many many prayers for you!
sir example five m wo rule apply nahi hoga k agar methyl group are presnt at equal distance from both side then choose the short branch site for number sindh text m likha hua hai
Sir in IUPAC,in 7 structure,there is one hydrogen atom at 6 carbon atom.But this carbon is bonded with only two carbon atoms.So it need two hydrogen atoms to complete its bond.Then number 6 carbon atom will become CH2.Please Sir pinned this comment for correction.
sir sry to bother you again and again but I wanted to ask why in 3,4-Diethyl-5-methyl-n-propyl octane firstly the "m" of methyl is not capital and why the carbon number at which the branch of n-prophyl occurred is not written before the functional group also neither the n or p is capital in this case(n-prophyl) time 20:51
sir assalamoalikum at 20:21 n propyl kaise likhain ge bcz ager straight chain per 2nd carbon per propyl group ho ga tu us waqt use n-propyl kah sakte hain baki conditions ma us ka common name tu use nahi ho sakta kindley ager ma kahin mis guide hon tu orrect kr dain sir
Assalam O Alaikum Sir 7) men hm ne 3,4-Diethyl-5-methyl-5-propyl octane kion nhi likha I mean propyl ki position kion mention nhi ki. secondly 4-Isopropyl heptane smjh nhi ye bhi nhi pata kion smjh nhi aya. And I'm still confused ke iso ki position kia ho gi wo second carbon pr hoti but in 4-Isopropyl heptane it is on 4th carbon.
Assalamualaikum sir.sir 20:36 pr prblm 7 ma apne n-propyl bata sir iski samajh nahi ae isko hum 5- propyl bi keh sakhte hy kiya aur agr nahi keh salhte tou ku nahi kahsakhte jazakallah 🦋

Sir you make organic chemistry possible and easy to understand otherwise it seems not possible to understand it sir jazakAllah thanks a lot sir many many prayers for you!
Sir g you really made organic chemistry easier for me .
Thanks alot Respected Sir may you live long and enjoy your life❤❤❤
Nice sir JAVED iqbal chemistry very very great prof ☺😊😀👌👌👌👌👌👍👍👍👍👍👍👍👏👏👏👏👏👏🔑🔊😄
1st ka answer ha'' 3-methyl pentane'' and 2nd ka haa ''2,4 dimethyl hexane'' .Am I right
You are right❤
3,5-dimethyl hexane nahi ha?
@@junaidstatus-js3539 apply lowest sum rule . your answer gives 7 whereas 2 4 dimethyl hexane gives 6 so no
No
@@junaidstatus-js3539start numbering from the side, from where the substituent gets lower number
Sir your lectures make this chapter so easier

Sir You deserve more success ❤
What a great sirMashaAllah... thank you sir ❤️🤌✨
I have question in 7th structure 20:27 can we give name like that 3,4-Diethyl-5-Methyl-5-Propyl
Sir 2,4-Dimethyl hexane answer hai ap kaa question ka thank u sir❤❤
Nice sir outstanding concept 👌👌👌👌👍👌
JazakAllah Sir🎉
Sir u say we write iso when 2nd carbon has methyl group but in isopropyl 2nd carbons has no mehtyl group
sir part 6 mein ethyl k sath methyl bh hai so then why u write di methyl instead of tri
Well-done Sir 👏👏👏👏👏👏👏
Lengend teacher ❤❤
Sir ya IUPAC ka part 7 ma hum n propyl ke jaga 5 propyl nahi likh sakta?
Amazing lecture 😊sir
Thank you so much sir you are great
Sir kindly tell important topics of whole book

Sir g hamari book pa no of corbon ma 1 ko methyle kahta ha or 2 ko ethyle kia ya sahi ha ma kafi confused hu 😢
Sir g plz bata daan
@OnlyFazal-k3t same thing
sir 7 structure main 6th carbon per 2 hydrogens atom han ap an Ek lagaya 😇😇
Yes bahi
Great sir your explanation is great❤❤❤❤
Amazing teaching method ❤
sir bahtareen lecture😊😊😉😉😉
sir example five m wo rule apply nahi hoga k agar methyl group are presnt at equal distance from both side then choose the short branch site for number sindh text m likha hua hai
Sir question no 11 mai
Ethyl isopropyl methyl methane hai to yaha per total 1 carbon hai to baki kay carbon apny marzi sy kaisa lagaya apnay ???
3-Ethyl butane
2,4-Dimthyl haxane
Yes
2,5 dimethyl hexane last question ka answer sir kindly bta den Sahi ha ya galat
Structure 7 mein 5 n propyl nhi hoga?
Sir last Homework ka name 2,4-dimethyl hexane hy ??? Kindly cnfrm krr den 🥰
yes Great ❤
good way sir
Wonderful outstanding sir
Sir I have question in 7th structure 20:27 can we give name like that 3,4-Diethyl-5-Methyl-5-Propyl
Sir you are lagent👌
Assalamo Alikum sir,
Sir why can't we say isobutyl even though hydrogen is removed from second carbon?
assalamualikum sir ethyl iso propyl methyl methane may arrangment kohe b kar saktay hain?
Yes
Good lectures sir amazing 😍😍
Sir in IUPAC,in 7 structure,there is one hydrogen atom at 6 carbon atom.But this carbon is bonded with only two carbon atoms.So it need two hydrogen atoms to complete its bond.Then number 6 carbon atom will become CH2.Please Sir pinned this comment for correction.
Ok beta writing kerty waqat ho gia ho ga
Yess...you are right
Thank u❤
boht axha tha sir ☝☝☝☝😍😍❤❤
Aoa
Sir 7th structure mein ham ne propyl ke sath n kiun lagaya!
Your choice
B/C dear it is normal (n)
sir sry to bother you again and again but I wanted to ask why in 3,4-Diethyl-5-methyl-n-propyl octane firstly the "m" of methyl is not capital and why the carbon number at which the branch of n-prophyl occurred is not written before the functional group also neither the n or p is capital in this case(n-prophyl) time 20:51
2,4-dimethylhexane
2,4-Dimethyl hexane
Yes
Sir yeh kasa pata chala ga ka hmna yh methyl wghera uper lagana ha ya necha??
Its your choice beta both are correct
Awaiting next chapters video
Sir great lecture❤
(13) 3 methyl pentane
(14) 2,4 dimethyl hexane
Sir plz chap wise lectures krwa dyn 1st chp sy bht mshkil hy wrna to

Sir plz organic compounds waly chap ka link die
Waiting for you sir
Upload kena hai beta
Ok sir
Great lecture sir
MashAllah may ALLAH bless you sir ❤️🫂 I wish I could take physical classes from you💕
sir assalamoalikum
at 20:21
n propyl kaise likhain ge bcz ager straight chain per 2nd carbon per propyl group ho ga tu us waqt use n-propyl kah sakte hain baki conditions ma us ka common name tu use nahi ho sakta
kindley ager ma kahin mis guide hon tu orrect kr dain sir
Assalam O Alaikum
Sir 7) men hm ne 3,4-Diethyl-5-methyl-5-propyl octane kion nhi likha I mean propyl ki position kion mention nhi ki.
secondly 4-Isopropyl heptane smjh nhi ye bhi nhi pata kion smjh nhi aya.
And I'm still confused ke iso ki position kia ho gi wo second carbon pr hoti but in 4-Isopropyl heptane it is on 4th carbon.
20:40 Sir ! Shouldn't the name be 3,4- Diethyl-5-methyl-5-propyl-octane ? why didn't you mention the location of the propyl side chain ?
Yes beta 5-propyl
Thanks for ask this Question ❤
Amazing lecture sir ❤❤❤
sir mdcat 2023 mein question aaya tha if both double and triple bond are present then ending given to the root is? iska answer enyne hoga ya ene?
yne
Structure 7 me propyl ki position ku ni likhni h
Graet sir
sir 9th wala 3-methyl hexane nhi ho sakhta?
sir qss ka ans hai
5-Ethyl 2,4, Dimethyl hexane
Sahih hai sir?
Plz confirm
Sir....'' dimethyl ethyl isopropyl methane ''ka structure kasa bana gaa plz bata dan🥲🥲🥲
See notes of activity of alkenes link given hai for notes community mai
ok sir thnx@@chemistrybyprof.javediqbal
Incredible 😍
29:02 1st ka answer hai 3-Methyl Pentane aur 29:31 2nd ka answer hai 2,4-Dimethyl Hexane
Assalamualaikum sir.sir 20:36 pr prblm 7 ma apne n-propyl bata sir iski samajh nahi ae isko hum 5- propyl bi keh sakhte hy kiya aur agr nahi keh salhte tou ku nahi kahsakhte jazakallah 🦋
Yes beta 5-n-propyl by mistake 5,missing hai
@@chemistrybyprof.javediqbal jazakallah sir ❤️
sir in IUPAC NAME 4 why you can't write 2,2,4-iso trimethy pentane?
please ask me.
For iso only one methyl at second position in whole chain for neo twao methyl at second position in whole chain
Sir at no 8 point you said that n cannot use for ethyl but here why you use n_ propyl
3,4_ Diethyl_5_methyl_n_propyl octane
It is a rule it is used for three or more than three carbon
Because ethyl has only one radical as its both carbons are equaivelent.
Sir homework questions me 1 ka answer 3-Methylpentane or 2 question ka answer 2,4-Dimethylhexane he
