Among the compounds `BF_(3), NCI_(3), H_(2)S, SF_(4)` and `BeCI_(2)`., identify the ones in which the central atom has the same type of hybridisation

Options

A. `BF_3, NCl_3`, and `H_2S`
B. `H_2S` and `BeCl_2`
C. `NCl_3` and `H_2S`
D. `BF_3` and `NCl_3`

Answer

C

Explanation

`SN` of `B` in `BF_3` is `3+0=3`, `SN` of `N` in `NCl_3` is `3+1=4`, `SN` of `S` in `H_2S` is `2+2=4`, `SN` of `S` in `SF_4` is `4+1=5`, and `SN` of `Be` in `BeCl_2` is `2+0=2`. Thus, `N` in `NCl_3` and `S` in `H_2S` are `sp^3`-hybridized.
