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.

Answer»

(ii)
(III) and (IV)
(i) and (iv)
(ii) and (iii)

Solution :(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)
