Question

Problem 12.19
Explain why (CH),C is more stable than
CH,CH, andCH, is the least stable
cation​

Answer 1

Answer:

Solution :

has nine

-hydrogens and hence has nine hyperconjugation structures while

has only three

-hydrogens and hence has only three hyperconjugation structures. As a result, is more stable.

In contrast in ,

the vacant p-orbital is perpendicular to the plane in which the three C-H bonds lie and hence cannot overlap with it.

Thus,  is not stabilized by hyperconjugation and hence is the least stable of the three cations

Hope it helps you

Plz mark me as brainliest

Answer 2

Answer:

Explanation:

• It is because , the hyper conjugation effect which is a reverse of inductive effect. The no of H-atom at Carbon is zero so it will face less hyper conjugation effect.
