Interpretation Introduction

Interpretation:

To analyse whether the given statement: tert-Butylamine is 30 amine, is true or not.

Concept Introduction:

Amines are the derivatives of ammonia, wherein one or more than one hydrogen atoms are substituted by an alkyl or aryl group.

The amines are categorized as primary, secondary or tertiary based on the number of carbon atoms that are bonded directly to the nitrogen atom. Primary amine has only one carbon atom bonded to the nitrogen atom. Similarly, secondary amines have two carbon groups bonded to the nitrogen, and tertiary amines nave three carbon groups bonded to the nitrogen.

Answer to Problem 1P

The statement is false.

Explanation of Solution

The structure of a tert-butylamine is given below:

Interpretation Introduction

Interpretation:

To analyze whether the given statement: The NH₄+ and CH₄have the same number of valence electrons and both have tetrahedral geometry as per the VSEPR model is true or not.

Concept Introduction:

The VSEPR (Valence-shell electron pair repulsion) model predicts the shape of the molecules or ions by identifying the position of atoms connected to the central atom.

Answer to Problem 1P

The statement is true.

Explanation of Solution

The valence shell electron pair repulsion (VSEPR) theory determines the shapes and the geometry of a molecule. In a CH₄ molecule, one carbon atom is bonded to four hydrogen atoms with a single bond. In NH₄⁺, one nitrogen atom is singly bonded to four hydrogen atoms.

According to the VSEPR model, each bond represents a pair of electrons. Since both compounds have four bonds around the central atom, they contain eight valence electrons. Also, according to the VSEPR model, these four bonding regions are arranged in a tetrahedral manner so that they are as far away from one another as possible, giving the molecule a tetrahedral geometry. Therefore, this statement is true.

Amines are the derivatives of ammonia, wherein one or more than one hydrogen atoms are substituted by an alkyl or aryl group.

The amines are categorized as primary, secondary or tertiary based on the number of carbon atoms that are bonded directly to the nitrogen atom. Primary amine has only one carbon atom bonded to the nitrogen atom. Similarly, secondary amines have two carbon groups bonded to the nitrogen, and tertiary amines nave three carbon groups bonded to the nitrogen.

Answer 20

Answer to Problem 1P

The statement is true.

Answer 21

Explanation of Solution

If in an amine, the nitrogen is directly bonded to one or more aryl groups or aromatic rings, and then the amine is known as an aromatic amine.

For example, aniline is an aromatic amine, as it is attached to one aromatic ring benzene. The structure of aniline is given below:

Answer to Problem 1P

The statement is true.

Explanation of Solution

In a heterocyclic amine, the carbon group of the ring structure is replaced by the nitrogen atom. For example, in pyridine, the nitrogen atom replaces one —CH group of the benzene ring.

Interpretation Introduction

Interpretation:

To analyze whether the given statement: The NH₄+ and CH₄have the same number of valence electrons and both have tetrahedral geometry as per the VSEPR model is true or not.

Concept Introduction:

The VSEPR (Valence-shell electron pair repulsion) model predicts the shape of the molecules or ions by identifying the position of atoms connected to the central atom.

Answer to Problem 1P

The statement is true.

Explanation of Solution

The valence shell electron pair repulsion (VSEPR) theory determines the shapes and the geometry of a molecule. In a CH₄ molecule, one carbon atom is bonded to four hydrogen atoms with a single bond. In NH₄⁺, one nitrogen atom is singly bonded to four hydrogen atoms.

According to the VSEPR model, each bond represents a pair of electrons. Since both compounds have four bonds around the central atom, they contain eight valence electrons. Also, according to the VSEPR model, these four bonding regions are arranged in a tetrahedral manner so that they are as far away from one another as possible, giving the molecule a tetrahedral geometry. Therefore, this statement is true.
