In which of the following compounds corban atom undergoes hybridisation of more than one type
(i) `CH_(3) CH_(2)CH_(2)CH_(3)`
(ii) `CH_(3) - CH = CH - CH_(3)`
(iii) `CH_(2) = CH - CH_(2) - CH_(3)`
(iv) `H - C -= C - H`

Options

A. (iii) and (iv)
B. (i) and (iv)
C. (ii) and (iii)
D. Only (ii)

Answer

c

Explanation

In (ii) `CH_(3) - CH = CH - CH_(3)`, rthe carbon atoms `C_(1)` and `C_(4)` are `sp^(3)` hybridised while `C_(1), C_(2)` and `C_(3)` are `sp^(2)`
In (iii) `overset(1)(CH)_(2)=overset(2)(CH)-overset(3)(CH)_(2)-overset(4)(CH)_(3)`
, the carbon atom `C_(1)` and `C_(2) are in `sp^(2)` while `C_(3), C_(4)` are in `sp^(3)` state of hybridised while in (iv) both carbon atoms are in `sp` state of hybridization
