Chapter 14, Problem 14.24UKC

(a)

Interpretation Introduction

Interpretation:

The line structure of thiol should be drawn.

Concept Introduction:

Thiols:

The general structure of thiol is $\text{R-SH}$, and it is also called as thioalcohols or mercaptans.

The arrangement of the atoms is explained by the graphical representation of molecular structure of chemical compound.

(b)

Interpretation Introduction

Interpretation:

The disulfides should be drawn from the oxidation reaction of 2-pentanethiol.

Concept Introduction:

Thiols:

The general structure of thiol is $\text{R-SH}$, and it is also called as thioalcohols or mercaptans.

Oxidation of thiols:

Thiol undergoes oxidation using ${\text{O}}_{\text{2}}$ (mild oxidizing agents) or ${\text{Br}}_{\text{2}}$ (mild oxidizing agents) which yields disulfides ($\text{RS-SR}$). During the oxidation reaction two thiols are joining together, and a new bond forms between the two sulfur atoms.
