Correct order of bond angles in the given compounds is/are:

a) γ<γ′\gamma < \gamma' b) γ<β=α\gamma < \beta = \alpha c) α>α′\alpha > \alpha' d) β>β′\beta > \beta'

A

γ<γ′\gamma < \gamma'

B

γ<β=α\gamma < \beta = \alpha

C

α>α′\alpha > \alpha'

D

β>β′\beta > \beta'

Answer

a, b

Explanation

Solution

The molecules are identified as CF2OCF_2O and CCl2OCCl_2O. Their experimental bond angles are compared with the given options. For CF2OCF_2O, O-C-F ≈110.3∘\approx 110.3^\circ and F-C-F ≈108.4∘\approx 108.4^\circ. For CCl2OCCl_2O, O-C-Cl ≈111.7∘\approx 111.7^\circ and Cl-C-Cl ≈116.6∘\approx 116.6^\circ. Comparing these values, options a) (γ<γ′\gamma < \gamma') and b) (γ<β=α\gamma < \beta = \alpha) are found to be true.
