Chapter 10, Problem 10.55P

Interpretation Introduction

Interpretation: The validation of the fact that addition of $\text{HCl}$ is not a stereospecific reaction by using cis and trans $\text{hex}-3-\text{ene}$ is to be stated. The structure of the stereoisomers formed from the given reaction is to be drawn.

Concept introduction: Electrophilic addition reaction follows Markovnikov rule. According to Markovnikov’s rule, the positive part of halogen acid attached to that carbon atom in $\text{C=C}$ bond which carries higher number of hydrogen atoms and the negative part of halogen acid will attach to that carbon atom in $\text{C=C}$ bond which has lesser number of hydrogen atoms.

A compound exhibits stereoisomers when it contains more than one stereogenic centers. The maximum number of stereoisomers a compound with $\text{n}$ number of stereogenic centers can show is $2^{\text{n}}$. A carbon atom which is bonded to four different groups is termed as chiral center or stereogenic center.
