[Prince III]

I Believe it was A Bond energy also increases

 

[gary221]

Actually the ques was
1 bond length increases
2 bond energy decreases
3 bond polarity decreases... or sth like tht..
Nywy, I did A

 

[donorsolutions]

it was given that only organic products were extracted!! for that we wont count Na mass!

Sodium Ethanoate ( CH3COONa) is an organic compound !

 

[donorsolutions]

n in cracking one.....WXYZ ??? i go wid A...all of thm...i thnk im wrng

That Was W,X,Z because
Cracking Of Alkane gives : Alkene and Alkane
Similarly Cracking Of Alkene (as in the question) gives : Di Alkene and Alkene

[Farah1996]

No the Answer Was B
A very bright student told me that he did 50 % 50 % but he himself asures the answer was B
dont really remember the percentages :/

it was 57% and sth 40sth

 

[angelicsuccubus]

D is correct

oh I think I was confused between b/d.. do you remember the q no?

 

[Farah1996]

What was the Incomplete outershell one?

Ch3+

 

[angelicsuccubus]

It wasnt 50% 50%. it was 60 something and 30 something i think. it was a sodium salt plus alcohol.

no no .. thats what i did.. I made the salt and alcohol first.. so that was giving 60, 30 first.. but then if you made the carboxylic acid and alcohol.. it was Exactly 50% 50%

 

[Farah1996]

its D for incomplete no. of shells

nope, it was ch3+

 

[Farah1996]

Can anyone confirm it?

Yes, its NOT 50% 50%
its 57%, aka C
