Me_2C=CH_2 is more stable than MeCH_2CH=CH_2 because of the Hyperconjugation.

Explanation:

In Me_2C=CH_2 with respect to Alkene the number of alpha-Hydrogen atoms are 6 (ie the number of hydrogen atoms taking part in hyperconjucation ).

While in MeCH_2CH=CH_2 , the number of alpha-Hydrogen atoms are 2.

So, the extent of hyperconjugation is more in Me_2C=CH_2 than in MeCH_2CH=CH_2.

Thus, Me_2C=CH_2 si more stable than MeCH_2CH=CH_2.

Hyperconjucation as explained in book by Paula Y. Bruice :-
