A method for the preparation of propanamine from chloroethane should be given. Concept introduction: Amines are the class of organic compounds that contains a nitrogen atom. Amines are commonly classified as primary, secondary and tertiary amines. The classification is based on the number of alkyl groups directly attached to the nitrogen atom. Amine group can be introduced to a carbon chain by the use of cyanide anion because it can be reduced to an amine group. Nucleophilic substitution reaction ( S N 2 ) is a single step substitution reaction in which electron rich species substitute leaving group. The attack takes place from the back side of the electrophilic center thus an inversion of the configuration takes place. Also, there is a single transition state because bond breaking and bond making occurs simultaneously.

Interpretation Introduction

Interpretation:

A method for the preparation of propanamine from chloroethane should be given.

Concept introduction:

Amines are the class of organic compounds that contains a nitrogen atom. Amines are commonly classified as primary, secondary and tertiary amines. The classification is based on the number of alkyl groups directly attached to the nitrogen atom.

Amine group can be introduced to a carbon chain by the use of cyanide anion because it can be reduced to an amine group.

Nucleophilic substitution reaction (SN2) is a single step substitution reaction in which electron rich species substitute leaving group. The attack takes place from the back side of the electrophilic center thus an inversion of the configuration takes place. Also, there is a single transition state because bond breaking and bond making occurs simultaneously.

Using reaction free energy to predict equilibrium composition Consider the following equilibrium: 2NOCI (g) 2NO (g) + Cl2 (g) AGº =41. kJ Now suppose a reaction vessel is filled with 4.50 atm of nitrosyl chloride (NOCI) and 6.38 atm of chlorine (C12) at 212. °C. Answer the following questions about this system: ? rise Under these conditions, will the pressure of NOCI tend to rise or fall? x10 fall Is it possible to reverse this tendency by adding NO? In other words, if you said the pressure of NOCI will tend to rise, can that be changed to a tendency to fall by adding NO? Similarly, if you said the pressure of NOCI will tend to fall, can that be changed to a tendency to rise by adding NO? yes no If you said the tendency can be reversed in the second question, calculate the minimum pressure of NO needed to reverse it.
