Answer 2

HELLO DEAR,

QUESTION:-If number of σ and π bonds in tetracyanoethylene [C2(CN)4], are a and b respectively, then a-b=?

ANSWER:- The structural formula of [C2(CN)4] ,.

CN. CN

\ C=C. /

/ \

CN CN

In structural formula ,there are 4 single bond and 1 double bond.

So, 1 single bond = 1 σ

1 double bond = 1 σ , 1 π

Therefore 4 single bond = 4 σ

1 double bond = 1 π

So, a = 4 and b= 1

a - b = 4 - 1

= 3. ANSWER.

I HOPE IT'S HELP YOU DEAR,

THANKS.
