Q.5 A n aqueous solution of hydrazine (N2H4) is electrochemically oxidized by O2, thereby releasing
chemical energy in the form of electrical energy. One of the products generated from the
electrochemical reaction is N2(g).
A, C given
It should be A, C, D
Where D is : Oxides of nitrogen are major by-products of the electrochemical process.
Yeah bro ,I searched in Google too.oxides will also be released
Q 6 p2
If first sncl2 is used cyanude converts into aldehyde and again upon using nabh4 it turn aldehyde into alcohol
Why are you going to challenge this ????
Yes, you are absolutely right
Ikr they are so dumb
Q.6 - Ans: C & D bcoz using NaBH4 after SnCl2/ Hcl ( Stephen's red.) can reduce aldehyde into alcohol so option A is wrong.
Exactly
Arey Bhai mechanism padhi hoti to samajh aata na ... SnCl2 se direct CHO banta hi nhi hai ... Pehle imine banta hai aur imine ka hydrolysis krne par aldehyde Banta hai....yahan par imine banega aur end m hydrolysis hoga to fir banega end m aldehyde... Sirf reaction yaad karega to tera option 1 galat hoga ... Otherwise wo sahi hai.
@@uchihaitachi1826 Bhai beech me nabh4 dal diya hei vo emine ko maine me covert krdega fir hydrolyse krnae pe alcohol banega naki aldehyde
In Q16 p2 , ans should be 3 or 2 .
3KI + 2[K3(Fe(CN)6)] --> 2K4[Fe(CN)6] + KI3
It is also possible, if not necessary to reduce ki3 to i2 .
Pls challenge this also.
Bhai tune krdiya na challenge?
@@dhairyapatidar2006bhai challenge kiya kya kisine, i also answered it 3 😢
Jee adv is different possibilities to find ans right? To iso electronic 1 and 3 dono nhi ho skte alag alag sochne pr
Correct answer is 4
3 h bhai jane do
Ha bhai 1 bhi hona chahiye 😢
Bhai ye to sabko pta ha ki aise questions ko EAN se hi approach kiya jata ha vo to pta nhi sab 1 kyu khene lge exact answer to 3 hi ha bhai
1 hoga@@thesanatanscientific1390
SnCl2 HCl se CH=NH banega. Hydrolysis nahi de rakhi hai vo last step me di hai. Us se pahle NaBH4 reduction karke use CH2-NH2 bana dega. So question is correct.
Par ether ko to H3O hi karega na to A ana cahiye
4:11
As you say it converts aldehyde into alcohol. Hence cho will be converted to ch2oh. So sir your approach is wrong... And c and d will be only right answers....
obviously bro
Paper 2 Q6 ka answer bilkul shi hai, agar NaBH4 ko Sncl2/Hcl ke baad use karte hai toh jis -CN ko -CHO mei convert kiya tha stephen se wo -CH2OH mei convert ho jaayega NaBH4 se
Exactly
Nahi bhai. preparation of carbonyl compound vala part dekho NCERT me. Sncl2/HCl se imine banta hai bas. H30+ ke baad vo aldehyde banta hai.
Beech mai nabh4 hai😂 vo bhul gaye sahi hai ans
Sncl2/Hcl don't Directly gives CHO group but it first reduces CN to CH=NH then it is hydrolysed to give CHO..see mechanism of this reaction
Sir In Ques 6..
Sncl2 /hcl ke baad Turant paani use karte tbb shi hota n...Bcz uske baad agar Sidha SBH daalenge toh Phir Imine jo bana hai Wo amine mein chala jayega Panai daalne pe wo CHO mein jaata..
usually sncl2/hcl as a reagent ke saath h2O dala hai that's a given. but i understand your approach so i guess acd or cd should be final
@@prachijain6077 But when You Look At the mechanism Carefully Sncl2 /Hcl upon addition to CN will Form Imine..
And Thereafter Upon Hydolysis It will form CHO..
But They Are directly using SBH which will definately Reduce Imine to amiine..
And So Only two options will be corect..
Using NaBH4 after SnCl2 will reduce the aldehyde to alcohol which is not needed in this question.
Sir pls clickbait nhi kijiye, thumbnail alag , actual chizein alag yeh bonus nhi honge ques , different ans diye jate hai ( no hate ) just a positive suggestion
Master kisne bnaya bhai tumhe A option mein. Jb sncl2 dal kr cho bna diya h uske baad nabh4 kiya h toh cho rhega thodi at the end vo oh bn jayega or ans mein cho chaiye
Exactly that's what I thought and marked only c and d
Arey Bhai mechanism padhi hoti to samajh aata na ... SnCl2 se direct CHO banta hi nhi hai ... Pehle imine banta hai aur imine ka hydrolysis krne par aldehyde Banta hai....yahan par imine banega aur end m hydrolysis hoga to fir banega end m aldehyde... Sirf reaction yaad karega to tera option 1 galat hoga ... Otherwise wo sahi hai.
Kisi n chem p1 m enthalpy wale question m 8000 Kiya h challenge yaadi hm deltaH /deltaU=Y se kre to 8000 aayga lekin 8120 diya
Same
8120 hi sahi h bhai
woh linlard reagent me ans c or acd dena chahiye keval cd denge woh toh nahi chalega
A nehi hoga
Because after sncl2/hcl cn will become Cho then after nabh4 Cho will become ch3oh
Arey Bhai mechanism padhi hoti to samajh aata na ... SnCl2 se direct CHO banta hi nhi hai ... Pehle imine banta hai aur imine ka hydrolysis krne par aldehyde Banta hai....yahan par imine banega aur end m hydrolysis hoga to fir banega end m aldehyde...

Mera 130 ban Rahe the kasam se heart attack agaya fir key se chem Mai 12 marks add uhe
Expected sai Kam tha but 142 bhi teek hai
Are after sncl2 plus hcl it will not convert into aldehyde it will convert into aldimine
Sir aap nabh4 se c=n ko c-n kyu nhi bna rhe A mein
Paper 2 ka chemistry ka 6 questions abcd hona chahiye
Bro wth
wright
Beta organic dhyaan se nhi padhi tumne
Agar ncert bhi theek se padhi hoti to tumhe pta chalta
Abcd hi hoga answer smja n @bitasingh
@@Carromking567 kisi haal me ni hoga Bro
Q6 nabh4 will reduce aldehye sir
Sir bonus krwa rahe ho ya jisko no mil rahe h uske kha rahe ho
Last question can be1 as well
Sir bonus marks dilwado 😢
A me Aldehyde banke bhi reduce ho jaayega NaBH4 se
Kya phy mein koi question bonus hai
Sir bonus dilwao pls 😢😢😢😢
Bhai bonus ma tabhi faida melaga agar tumara negative ho raha ho wo question
Bhai nhi bilcul nhi isse unka nuksan h jinhone koi particular approach se solve Kiya h
Thanks sir ❤❤❤❤❤
Bonus dilado sir
Koi bata sakta kitane marks ka bonus hai
Bahi tukke se 3 sahi hogaya mera 😂😂 😂😂

Are nice
Q no 6 sncl2 ke baad nabh4 se cho bhi alcohol me reduce ho jaega
Alcohol nahi Amine but yea it's wrong

EAN lagya hai jo ki shi hai
Exactly
The question(given compounds are of carbonylgroup )itself reveals that it's from EAN topic.
Just check the definition of "isoelectronic" by iupac.
Check jd lee for examples of isoelectronic species.

Glt h ans 1 and 3 dono dena chaiye
