1.	Explain why (underset(+)(C )H_(3))_(3) overset(+)(C ) is more stable than CH_(3)CH_(2) and CH_(3) is the least stable cation
Answer» Solution :Hyperconjugation interaction in `(CH_(3))_(3) overset(+)(C )` is GREATER than in `+CH_(3) overset(+)(C )H_(2)` as the `(CH_(3))_(3) overset(+)(C )` has nine `C-H` bonds. In `CH_(3)`, vacant p orbital is perpendicular to the plane in which `C-H` bonds lie, HENCE cannot overlap with it. THUS, `overset(+)(C )H_(3)` lacks hyperconjugative stability
