A) \[(III)>(II)>(I)>(IV)\]
B) \[(II)>(III)>(I)>(IV)\]
C) \[(I)>(II)>(III)>(IV)\]
D) None of the above
Correct Answer: A
Solution :
Aromatic or aryl ring provides more stable carbonium ion, while aliphatic alkyl groups provides less stability due to +1 effect of alkyl group. Generally stability of carbonium ion decreases in the following order. Triphenyl methyl carbonium > diphenyl methyl carbonium > benzyl carbonium > allyl carbonium > tertiary carbonium > secondary carbonium > primary carbonium > methyl carbonium.You need to login to perform this action.
