Question

Cyclic hydrocarbon 'A' has all the carbon and
hydrogen atoms in a single plane. All the carbon
carbon bonds have the same length, less than
1.54 Å, but more than 1.34 Å. The C-C-C
bond angle will be

(a) 109°28
(b) 100°
(C) 180°
(d) 120°

Answer 1

Answer:

option d

Explanation:

Hence all the properties mentioned in the suggested that it is a benzene molecule. since in benzene all carbon are sp^2 hybridised, therefore, c-c-c angle is 120°
