Which type of hybridisation of each carbon is there in the compound ?
`CH_(3)-CH=CH-CN`

Options

A. `sp^(3),sp^(2),sp^(2),sp`
B. `sp^(3), sp^(2), sp^(2), sp^(3)`
C. `sp^(3), sp^(2), sp^(3), sp^(3)`
D. `sp^(3), sp^(2), sp, sp^(3)`

Answer

A

Explanation

`H-overset(H)overset(|)underset(H)underset(|)("C"^(1))-overset(H)overset(|)("C"^2)=overset(H)overset(|)("C"^3)-overset(4)C-=N`
From left `1-sp^3,2-sp^2,3-sp^2,4-sp.`
