Chapter 10, Problem 25PP

(a)

Interpretation Introduction

Interpretation:

The isomer of given molecular formula should be identified.

Concept introduction:

Isomer: A molecule having same molecular formula with different chemical formula is called isomer.

Constitutional Isomers: A molecule having same molecular formula with different structural formulas (Difference in the connectivity of the molecule is called constitutional isomer).

(b)

Interpretation Introduction

Interpretation:

All four mono chlorination products have to be drawn.

Concept introduction:

Isomer: A molecule having same molecular formula with different chemical formula is called isomer.

Mono-chlorination: The alkyl group reacts with chlorine in presence of photochemical conditions to give mono-chlorinated product.

(c)

Interpretation Introduction

Interpretation:

The predominates product of bromination has to be drawn.

Concept introduction:

Radical Bromination:

2-methyl propane undergoes radical bromination which yields the 2-bromo-2-methylpropane because bromination will occur where the tertiary radical is present. (Bromination reactions are more selective reaction).

Bromination will occur on tertiary radical than the secondary than primary radical, tertiary radical is more stable radical than the other radicals.
