Chapter 27, Problem 62IAE

Interpretation Introduction

(a)

Interpretation:

The formula of the expected products in the given reaction should be written. Also, if no reaction occurs N.R. should be written.

Concept introduction:

Pyrrolidine is an organic compound that is also known as tetrahydropyrrole. It is a secondary amine and also a saturated heterocycle. It is a colorless liquid that is miscible with water and many organic solvents.

Interpretation Introduction

(b)

Interpretation:

The formula of the expected products in the following reaction should be written. Also, if no reaction occurs N.R. should be written.

${\left({\text{CH}}_3\right)}_4{\text{N}}^{+}\left(\text{aq}\right)+\text{HCl}\left(\text{aq}\right)\to$

Concept introduction:

Tetramethylammonium ion is the simplest quarternary ammonium cation. It consists of four methyl groups that are attached to a central nitrogen atom. It is isoelectronic with neopentane. It is a positively charged species and can only be isolated in association with the counterion.

Interpretation Introduction

(c)

Interpretation:

The formula of the expected products in the following reaction should be written. Also, if no reaction occurs N.R. should be written.

${\text{CH}}_3{\text{CH}}_2{\text{NH}}_2\left(\text{aq}\right)+{\text{OH}}^{-}\left(\text{aq}\right)\to$

Concept introduction:

Amines are the compounds that contain the basic nitrogen atom with a lone pair. These are the derivatives of ammonia when one or more hydrogen atoms get substituted by alkyl or aryl groups.

Interpretation Introduction

(d)

Interpretation:

The formula of the expected products in the following reaction should be written. Also, if no reaction occurs N.R. should be written.

${\left({\text{CH}}_3\right)}_3{\text{NH}}^{+}\left(\text{aq}\right)+{\text{OH}}^{-}\left(\text{aq}\right)\to$

Concept introduction:

The ammonium salts are the ionic compounds that are soluble in water. These are formed by the protonation of ammonia. Ammonium is the common name for the positively charged or protonated amines.

The general formula of ammonium salts is ${\left(\text{R}\right)}_4{\text{N}}^{+}{\text{A}}^{-}$.

Where,

• $\text{R}$ is hydrogen, alkyl or aryl groups.
• $\text{A}$ is an anion.
