Question

True or False.

The IUPAC name of \[ \text{CH}_3\text{CH}_2\overset{\substack{\textstyle \text{C}\rlap{\text{H}_2\text{OH}} \\[-0.2ex] \textstyle | \\[-0.2ex]}}{\text{C}}\text{HCH}_2\text{CH}_2\text{CH}_3 \] is butan-1-ol.

Answer 1

This statement is false.

Explanation:

The correct IUPAC name is 2-propylbutan-1-ol (or 2-ethylpentan-1-ol depending on the longest continuous carbon chain containing the −OH group). It is definitely not butan-1-ol, which only has 4 carbons in total.
