The hybridization states of carbon atom `(1)` and carbon atom `(2)` in the compound
`N-=overset(1)(C )-overset(2)(CH) =overset(3)(CH_(2))`
are, respectively,

Options

A. (1) `sp^(2)` and `sp`
B. (2) `sp` and `sp^(2)`
C. (3) `sp^(3)` and `sp`
D. (4) `sp` and `sp`

Answer

B

Explanation

`C-1` is `sp` hybridized as it forms `2 pi` bonds and `2 sigma` bonds while `C-2` is `sp^(2)` hybridized as it forms `3 sigma` and `1 pi` bond:
`N-=underset(1)overset(sp)(C)-underset(2)overset(sp^(2))(CH)=underset(3)(CH_(2))`
