Question

The Cl-C-CI angle in 1, 1, 2, 2-tetrachloroethene and tetrachloromethane respectively will be about

(a) 120° and 109.5°

(b) 90° and 109.5°

 (c) 109.5° and 90°

(d) 109.5° and 120°

Answer 1

Correct option (a) 120° and 109.5°

Explanation:

In 1,1,2,2-tetrachloroethene, each carbon is sp²-hybridised, thus having bond angle 120° and in tetrachloromethane carbon is sp³ -hybridised, hence bond angle is 109.5°.
