Chapter 7, Problem 7.26P

Interpretation Introduction

Interpretation: The structure of $1°,2°$ and $3°$ carbocation, that has molecular formula ${\text{C}}_{\text{4}}{\text{H}}_{\text{9}}{}^{+}$, is to be drawn and are to be arranged in order of increasing stability.

Concept introduction: An electron deficient carbon atom on which positive charge is present is known as carbocation. An electron deficient carbon atom bonded to one another carbon atom is termed as $1°$ carbocation. Whereas, an electron deficient carbon atom bonded to two and three carbon atoms is known as secondary and tertiary carbocation, respectively. The increasing order of stability of carbocation is $1°<2°<3°$.
