The `CI - C - CI` angle in `1, 1, 2, 2`, tetrachloroethone and tetrachloromethane respectively will be about:

Options

A. `120^(@)` and `109.5^(@)`
B. `90^(@)` and `109.5^(@)`
C. `109.5^(@)` and `90^(@)`
D. `109.5^(@)` and `120^(@)`

Answer

a

Explanation

In `1, 1, 2, 2` tratachloroethene, each carbon is `sp^(2)`- hybridized thus having bond angle `120^(@)` and in tetrachloromethane carbon is `sp^(3)` - hybridized, hence bond angle is `1095.5^(@)`.
