Mashallah Mam ap ny buhht acha explain kia....
🙏🙏
Thanks mam for helping me accomplish my goal.🙏🏻🙏🏻
Nice to see this ... best wishes for your future goals💐💐
Very nice explanation mam
💐💐
Mam you way of teaching is soooo nice 👍👍
Thank you soooo much💐
Fantastic 🎉🎉
Thanks 🤗
Too great lec❤
💐💐
Mam thankyousomuch

Mam ji thanks so much from Pakistan

Mam hm E,Z ma Example 4
Us ma hm phala carban hy same atomic n hn too hm next pr jye ga
Aur jitna atach hn bond un sab ka atomic number ko total ker ka phir priority dy ga
Many study kya
Kya ya thek hy
Sab ke atomic no ke total karne ki jaroorat nhi hai.humein sirf ek point of difference dekhna hai.. example 4 mei right waale C se attached dono group mei first atom C hai isliye next atom mei bus ek point par difference dekha oxygen ka atomic no Carbon se jyada hai isliye CH2OH ko jyada priority di
if -(C triple bond CH) group and C(CH3)3 is attached at one side of carbon then according to e and z system which group give priority
Mam plz jaldi reply kr dain hamara exam h with reason
C triple bond CH waale ko priority milegi beta.. Aap open karke likh ke dekho.. First atom to dono mei hi same priority waala hoga isliye hum second atom par jaayenge.. Second atom bhi dono groups mei carbon hi Hai but C triple bond waale mei ye carbon three carbon se attached Hoga jabki C(Ch3) 3 waale mei second carbon hydrogen se attached hai
mam -(C triple bond CH) Main Jab Ham open Karte Hain To 3 carbon hi Lage Hue hote hain aur dusre C(CH3)3 mein bhi teen carbon hi Lage hue hain to kis base py first group ko priority mily ge
Mam in dono ma to teeno teeno he carbon lagy hain to hm kya third next pr ni jain gen ???
❤
❤️❤️
Mam agr one side py CHO and CH2OH h to kis ko priority mily ge
CHO ko ..jab aap CHO ko open karke likhoge to first atom carbon se do oxygen ban jaayenge kyonki CHO mei C=O hota hai ..jabki ch2oh mei ek hi O hai
Thanks 😊😊
Or agr one side py -CHO and -OCH3 h to kis ko priority mily ge???
OCH3. ko priority milegi beta...first atom O hai..
Thank you so much mam😊😊
Mam ap ne ezsystem ki example no. 4 glt ki hai wha e system apply hota hai
Nhi beta z hi hoga.. Phir se ek baar dekho aur samjho.. Na samjh aaye to bataana
@@NOBLECHEMISTRY mam carbon 1 pr jhaa CH2OH wala group attach hai whaa se mam mujhe e system lga haiku k apne kha hai agr first atoms same ho to second ko chk krein second mei upr Hydrogen hai aur nichy carbon hai lakin ap ne oxygen aur carbon k drmian kia hai islie ab hydrogen ki priority km hai as compare to carbon
@@sofiaashraf7907 yahan Oxygen ko priority deni hai... Second atom hydrogen ko nhi dekhna.. Oxygen ko dekhna hai.. Second atom to hydrogen and oxygen dono hi Hai.. But priority oxygen ko hi di jaayegi as compared to hydrogen.. Phir neeche dekho.. Second atom carbon hi Hai..to Oxygen ki priority jyada Hai as compared to carbon..
@@NOBLECHEMISTRY ok mam thank you for your cooperation and ur method of teaching is outstanding
Mam has made no mistake. She has given the correct name according to the Cahn-Ingold-Prelog system of nomeclature. Here, in example no. 4, there are four different groups attached around the C and C double bond. The first atom of all the groups is carbon, so we have to look for the second atom in all of them to assign priority. Let's compare C(Me)3 with CH2-OH. There are three methyl groups attached to the carbon in C (CH3)3, and there are two hydrogen and one hydroxyl group in CH2-OH. The first atom of all three methyl groups is carbon, while the first atom in CH2-OH is two hydrogens and one hydroxyl group. Here, oxygen has an atomic number of 8, and carbon has an atomic number of 6. That's why we give priority to CH2OH over CH3. I hope it will help you.
Laaa jawaab jitnee tareeeef kroo utni km hai mam aap kaha sy belong krteeee hai

Madem g y channel free hy hr kisy kayly??
Haan ji beta

Mam please start bsc 3rd year syllabus
After stereochemistry i will start it
@@NOBLECHEMISTRY OK mam
E=z,Z=e😂😂😅
Haan beta..mujhe yahi tareeka easy lga yaad karne ke liye..
Ok mam but aap samjhate bahut acha hoo
Fantastic 🎉🎉
