Chapter 14, Problem 16P

(a)

Interpretation Introduction

Interpretation:

Preparation of 2-bromo-2-methyl from 2-methylpropane has to be shown.

Concept Introduction:

Radical or free radical: The unpaired valence electron of an atom, molecule, or ion is called as radical.

In a halogenation reaction, one or more halogen atoms are introduced into an organic compound. Generally, these reactions are initiated in the presence of light or heat.

Bromination:

(b)

Interpretation Introduction

Interpretation:

Preparation of 2-methyl-1- propene from 2-methylpropane has to be shown.

Concept Introduction:

Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical.

In a halogenation reaction, one or more halogen atoms are introduced into an organic compound. Generally, these reactions are initiated in the presence of light or heat.

Bromination:

(c)

Interpretation Introduction

Interpretation:

Preparation of 2-Iodo-2-methylpropane form 2-methylpropane has to be shown.

Concept Introduction:

Radical or free radical: unpaired valence electron of an atom, molecule, or ion is called as radical.

In a halogenation reaction, one or more halogen atoms are introduced into an organic compound. Generally, these reactions are initiated in the presence of light or heat.

Bromination:

Markovnikov’s rule:

Alkene undergoes hydro halogenation using hydrogen halide through breaking of carbon to carbon double bond, followed by the electrophilic addition of a hydrogen atom and halogen. The halide ion will add to the more substituted carbon in the alkene.
