Question
Chapter 4.16A, Problem 4.29P
Interpretation Introduction
Interpretation: The given carbocations are to be arranged in the decreasing order of their stability and each carbocation is to be classified as primary, secondary or tertiary.
Concept introduction: The stability of carbocation depends upon the position of positive charge on carbon atom. Carbocations are electron deficient, as a result they are more stable on tertiary carbon atom as compared to secondary or primary carbon atom.
To determine: The order of given carbocations in decreasing order of their stability and classification of each as primary, secondary or tertiary.
