Chapter 10: Problem 132

Thiols are named in the same manner as aleohols, but the suffix e of the parent alkane is retained and thiol added. \- In compounds containing other functional groups of higher precedence, the presence of \(-\$ M\) is indicated by the prefix werapto.

Short Answer

Expert verified
Answer: When a compound contains a thiol group and a functional group of higher precedence, the prefix "mercapto" is used to indicate the presence of the thiol group before the name of the parent compound.

Step by step solution

01

Naming Thiols

When naming thiols, the suffix "e" of the parent alkane is retained, and "thiol" is added as a separate word. For example, if we have an alkane named "methane," the corresponding thiol would be named "methane thiol."
02

Identifying Functional Groups of Higher Precedence

In compounds containing other functional groups with higher precedence, we use the prefix "mercapto" to indicate the presence of the thiol group. Some examples of functional groups with higher precedence than thiols are aldehydes, ketones, carboxylic acids, and esters.
03

Applying the Prefix 'Mercapto'

When other functional groups of higher precedence are present, we use the prefix "mercapto" before the name of the parent compound. For example, if we have a compound with a carboxylic acid and thiol group, we would first name the parent compound due to the carboxylic acid group (e.g., "ethanoic acid") and then add the prefix "mercapto" to indicate the presence of the thiol group (e.g., "mercaptoethanoic acid").

Take a proton away and simultaneously break a bond to give stable molecules or ions. Simultaneous proton transfer to solvent and lass of \(\mathrm{H}_{2} \mathrm{O}\) gives the carbon-carbon double bond of the terminal alkene.

Alcohols react with sulfonyl chlorides to give alkyl sulfonates. The sulfonate group is a good leaving group analogous to a halogen atom.

Two diastereomeric sets of enantiomers, \(A / \mathrm{B}\) and \(\mathrm{C} / \mathrm{D}\), exist for S-bromo-2-butanol.

When enantiomer \(\mathrm{C}\) or \(\mathrm{D}\) is treated with HBr, only meso 2,3-dihromobutane is formed; no racenaic 2,3-dibroenobutane is formed. Ancount for these oboervarions.
