Question

Explanation please !!


The correct order of increasing bond length of
C-H, C-O, C-C and C = C is
[AIPMT (Prelims)-2011]

(1 ) C-C<C-O<C-C< C = C

(2)C-H< C = C<C-O<C-C

(3) C-C< C = C < C-O<C-H

(4) C-O< C-H<C-C< C = C​

Answer 1

Answer:

(2) C−H<C=C<C−O<C−C

Explanation:

The C−H bond is the shortest due to the small size of both atoms & large electronegativity difference.  

The double bonds are shorter than single bonds.

Hence C=C<C−O and C-C

Due to electronegativity difference between C and O

C−O<C−C

∴ Correct order of increasing bond length is :

C-H < C=C < C-O < C-C

Hence, the correct option is B.
