Question

give reason for the order of stability of carbocation 3>2>1

please ans. it fast

Answer 1

Answer:

+I effect more the electron releasing group attached to carbocation more the density of electron increases on the carbocation so stability increases. So 3° carbocation is more stable. ... So tripheny carbocation is more stable. So stability order is 3°>tripheny carbocation> Allylic carbocation >2>1.

Answer 2

Answer: +I effect

Explanation: It is due to the +I effect of the alkyl groups present in the carbocation. Since 3 carbocation has more alkyl groups > 2 > 1 it exhibits more +I effect thereby stabilising the carbocation.

+I effect confers to the stability since the electronic donating nature of the alkyl group will reduce the positive charge upon the carbon of the carbocation hence it will be more stable
