Chapter 22.2, Problem 10SSC

Interpretation Introduction

(a)

Interpretation:

The functional group present in the given structure needs to be determined and the name of the substance needs to be given.

Concept introduction:

The functional group is the group present on the main carbon chain of an organic compound. It determines the chemical properties and the type of reactions an organic compound can show. The name of the group depends on the atoms present in the group for example an −OH group contains O and H atom thus, it is a hydroxyl group. The different functional groups are named according to IUPAC rule.

Name of some functional groups are: -OH: alcohol, -CHO: aldehyde, -COOH: carboxylic acid etc.

Answer to Problem 10SSC

Functional group-amino

Name of the substance-propan-2-amine

Explanation of Solution

The given compound is as follows:

There are 3 carbon atoms and one − ${\text{NH}}_{\text{2}}$ group present in it. Here, − ${\text{NH}}_{\text{2}}$ group is functional group. The name of the group is amino. The 3 carbon atoms show the root name is “prop” and amino group is at 2^nd position thus, the name of the substance is propan-2-amine.

Answer to Problem 10SSC

Functional group-hydroxyl

Name of the substance- cyclohexanol

Explanation of Solution

The given organic compound is as follows:

There are 6 carbon atoms in the cyclic form and one −OH group present in it. Here, -OH group is functional group. The name of the group is hydroxyl. This is the functional group for alcohol. The suffix “-ol” is used for alcohols and since there are 6 carbon atoms the root name will be “hexan”. This is a cyclic group thus, prefix “cyclo-“will be used.

Therefore, the name of the compound will be cylclohexanol.

Answer to Problem 10SSC

Functional group-ether

Name of the substance- 1-methoxypropane

Explanation of Solution

The given organic compound is as follows:

There are 3 carbon atoms in the cyclic form and one − ${\text{OCH}}_{\text{3}}$ group present in it. Here, - ${\text{OCH}}_{\text{3}}$ group is functional group. The name of the group is ether. The prefix “-metoxy” is used for this functional group because there is one methyl and one oxygen atom present. Since there are 3 carbon atoms the root name will be “prop”.

Therefore, the name of the compound will be 1-methoxypropane.
