Draw the structures of butan-1-ol and hexanoic acid.

a) Draw the structures of the following:

i) Butan-1-ol
Butan-1-ol is an alcohol with four carbon atoms in a straight chain and an -OH group attached to the first carbon.

$$\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{OH}$$

The structural formula is:

$$\boxed{ \begin{matrix} \text{H} & \text{H} & \text{H} & \text{H} \\ | & | & | & | \\ \text{H} - \text{C} - \text{C} - \text{C} - \text{C} - \text{O} - \text{H} \\ | & | & | & | \\ \text{H} & \text{H} & \text{H} & \text{H} \end{matrix} }$$

ii) Hexanoic acid
Hexanoic acid is a carboxylic acid with six carbon atoms in a straight chain, including the carbon in the carboxyl group (-COOH).

$$\text{CH}_3\text{CH}_2\text{CH}_2\text{CH}_2\text{CH}_2\text{COOH}$$

The structural formula is:

$$\boxed{ \begin{matrix} \text{H} & \text{H} & \text{H} & \text{H} & \text{H} & \text{O} \\ | & | & | & | & | & \parallel \\ \text{H} - \text{C} - \text{C} - \text{C} - \text{C} - \text{C} - \text{C} - \text{O} - \text{H} \\ | & | & | & | & | \\ \text{H} & \text{H} & \text{H} & \text{H} & \text{H} \end{matrix} }$$
