Question

Arrive at, systematically, the IUPAC name of the compound: CH₃ -CH₂ – CH₂ -OH.

Answer 1

Step 1: The parent chain consists of 3 carbon atoms. The root word is ‘Prop’. 

Step 2: There are single bonds between the carbon atoms of the chain. So, the primary suffix is ‘ane’.

Step 3: Since, the compound contains – OH group, it is an alcohol. The carbon chain is numbered from the end which is closest to – OH group. (Rule 3)

Step 4: The locant number of – OH group is l and thus the secondary suffix is ‘l-ol’. 

The name of the compound is Prop + ane + (l – ol) = Propan-l-o
