MeCH(2)CH=CH(2) is stable than Me(2)C=CH...

`MeCH_(2)CH=CH_(2)` is stable than `Me_(2)C=CH_(2)`because-

A

inductive effect of Me - group.

B

resonance effect of Me - group.

C

hyperconjugative effect of Me - group.

D

resonance and indutive effects of Me - grouo.

Text Solution

Verified by Experts

The correct Answer is:
C
`MeCH_(2)CH=CH_(2)("two" alpha"H-atoms")`
`Me_(2)C=CH_(@)("six"alpha"H-atoms")`
Greater the number of H - atoms `(alpha "H-atoms")` attached to the `alpha` carbon with respect to the double bond, more will be the hyperconjugative stability of the alkene.
