The hyperconjugative stabilities of tertiary — butyl carbocation and but-2— ene, respectively, are due to
A
(empty) and 
electron delocalisations.
B
and 
electron delocalisations.
C
(filled) and 
lectron delocalisations.
D

and electron delocalisations.
Text Solution
Verified by ExpertsThe correct answer is:
A
(empty) and 
electron delocalisations.
Hyperconjugation involves delocalisation of 
electron of a C-H with 
empty p-orbital. It increases stability of carbocation, free radical and alkenes by decreasing energy.
CH 3 - CH = CH 2 ( 
electron) delocalization
