Which of the following molecules possess `sp,sp^2` and `sp^3` hybridized C atoms?

Options

A. but-2-yne
B. buta-1,3-diene
C. buta-1,2-diene
D. propadiene

Answer

C

Explanation

`underset((1))(overset(sp^(3))(CH_3)overset(sp)(C)-=overset(sp)(C)overset(sp^(3))(CH_3))`
`underset((2))(overset(sp^(2))(CH_2)=overset(sp^(2))(CH)-overset(sp^(2))CH=overset(sp^(2))(CH_2))`
`underset((3))(overset(sp^(2))(CH_2)=overset(sp)(CH)=overset(sp^(2))(CH)-overset(sp^(3))(CH_3))`
`underset((4))(overset(sp^(2))(CH_2)=overset(sp)(C)=overset(sp^(2))(CH_2))`
