Chapter 22, Problem 27P

Interpretation Introduction

Interpretation:

The structural formulas for all the isomers of molecular formula ${\text{C}}_7{\text{H}}_9\text{N}$, and the acceptable name for the each formulas is to be given; the strongest base among the four isomers is to be identified; the isomer that gives $N\text{-nitroso}\text{amine}$ when reacts with sodium nitrite and hydrochloric acid is to be determined; the isomer that undergoes nitrosation of their benzene ring when it reacts with sodium nitrite and hydrochloric acid is to be identified.

Concept Introduction:

The systematic naming of organic compound is given by IUPAC nomenclature. The naming of organic compound is done such that the structure of organic compound is correctly interpreted from the name. If the molecular formula of two compounds is same but their atoms are connected in different ways, then they are known as constitutional or structural isomers.

The $\text{p}{K}_{\text{a}}$ value is directly related to the basic strength of the compound. The major factors that contribute to the basic strength are $\text{s}$ character, inductive effect and polarity.

The conversion of organic compounds into nitroso derivative is known as nitrosation. In nitrosation, compound contains $\text{R}-\text{NO}$ functionality. The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The replacement or substitution of one functional group with another different functional group in any chemical reaction is termed as substitution reaction. The substitution reaction involves the replacement of one functional group by other functional group.
