Which of the following compounds does not have only one type of hybrid carbon atoms ?

Options

A. `HC-=C-C-=CH`
B. `CH_(3)CH_(2)-CH_(2)-CH_(3)`
C. `CH_(3)-C-=C-CH_(3)`
D. `CH_(2)=CH-CH=CH_(2)`.

Answer

C

Explanation

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