In which of the compounds given below is there more than one kind of hybridisation `(sp,sp^(2),sp^(3))` for carbon ?
(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. (ii)
B. (iii) and (iv)
C. (i) and (iv)
D. (ii) and (iii)

Answer

D

Explanation

(i) `CH_(3)CH_(2)CH_(2)CH_(3)" (all "sp^(3)" C atoms)"`
(ii) `CH_(3)-CH=CH-CH_(3)" ("sp^(3)" and "sp^(2)" C atoms)"`
(iii) `CH_(2)=CH-CH_(2)(sp^(2) " and "sp^(3)" C atoms")`
(iv) `HC-=C-H" (all sp C atoms)"`
Correct answer (D) : (ii) and (iii)
