Which of the following molecules possesses more than one type of hybridized carbon?
`CH_(3)CH_(2)underset((A))(CH_(2))CH_(3)` , `CH_(3)CH underset((B))=CHCH_(3)`
`CH_(2)=underset((C ))(CH)-C-=CH` , `HCunderset((D))-=CH`

Options

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

Answer

A

Explanation

`overset(sp^(3))(CH_(3))overset(sp^(2))(CH)underset((B))=overset(sp^(2))(CH)overset(sp^(3))(CH_(3))` , `overset(sp^(2))(CH_(2))overset(sp^(2))(CH)underset((C))=overset(sp)(C)-=overset(sp)(CH)`
`overset(sp^(3))(CH_(3))overset(sp^(3))(CH_(2))underset((A))overset(sp^(3))(CH_(2))overset(sp^(3))(CH_(3))` , `overset(sp)(CH)underset((D))-=overset(sp)(CH)`
