Chapter 12, Problem 27P

(a)

Interpretation Introduction

Interpretation:

The alkane with molecular formula, ${\text{C}}_{\text{5}}{\text{H}}_{\text{12}}$ that forms only one monochlorinated product when heated with ${\text{Cl}}_{\text{2}}$ has to be given.

Concept introduction:

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

Bond strength is depends on the formation of the radical, if the radical is involving in resonance which is weakest bond strength.

Chlorination:

2-methyl propane undergoes radical chlorination which yields the 2-bromo-2-methylpropane and 1-bromo-2-methyl propane.

(b)

Interpretation Introduction

Interpretation:

The alkane with molecular formula, ${\text{C}}_7{\text{H}}_{\text{16}}$ that forms seven monochlorinated products when heated with ${\text{Cl}}_{\text{2}}$ has to be given.

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

Bond strength is depends on the formation of the radical, if the radical is involving in resonance which is weakest bond strength.
