Question

Sometimes it is helpful to look at $3 D$ models of organic molecules. Match these models $(1 - 3)$ with their structural formulae (a-c) and work out their IUPAC names.

1.	a. ${CH}_{3} - CH = {CH}_{2}$
2.	b. ${CH}_{3} - {CH}_{2} - {CH}_{3}$
3.	c. ${CH}_{3} - {CH}_{2} - {CH}_{2} - OH$

Accepted Answer

1.

The structural formula of the above compound is $(1 - 3)$ .

The IUPAC name of the compound can be found as,

The longest carbon chain is three carbons long, and so the parent chain is prop-

It contains a hydroxyl functional group. Therefore, its suffix is -ol.

Numbering is done from right to left so that the functional group is in the lowest possible position.

The IUPAC name for this molecule is Propan- $1$ -ol or propanol.

2.

The structural formula of the above compound is ${CH}_{3} - CH = {CH}_{2}$ . It is an alkene.

The IUPAC name of the compound can be found as,

The longest carbon chain is three carbons long, and so the parent chain is prop-

The molecule contains a carbon-carbon double bond so the suffix is -ene.

Numbering is done from right to left so that the unsaturated carbon-carbon double bond is in the lowest possible position. The double bond follows carbon- $1$ .

The IUPAC name for this molecule is Prop- $1$ -ene or Propene.

3.

The structural formula of the above compound is ${CH}_{3} - {CH}_{2} - {CH}_{3}$ . It is a saturated hydrocarbon.

The IUPAC name of the compound can be found as,

The longest carbon chain is three carbons long, and so the parent chain is prop-

The molecule is a saturated compound. Therefore, the suffix is -ane. It does not contain any functional group also.

The IUPAC name for this molecule is propane.

1.    a. ${CH}_{3} - CH = {CH}_{2}$

2.    b. ${CH}_{3} - {CH}_{2} - {CH}_{3}$

3.    c. ${CH}_{3} - {CH}_{2} - {CH}_{2} - OH$
