Question
Arrive at, systematically, the IUPAC name of the compound: CH3 – CH2 – CH2 – OH.
Short Note
Solution
- Step 1: The parent chain consists of 4 carbon atoms. The root word is ‘but’.
- Step 2: All are single bonds between the carbon atoms of the chain. So the primary suffix is ‘ane’.
- Step 3: Since the compound contains the -OH group, it is an alcohol. The secondary suffix is ‘ol’.
But + ane + ol = Butan-ol = Butanol.
