Write the IUPAC names of the following structural formulae:
✓
Answer
The number of carbon atoms in the longest chain: 4
Parent alkane: Butane Functional group: -OH (ol)
Assign the number:
The carbon atom to which the $-\mathrm{OH}$ group is attached is numbered as $\mathrm{C}_2$. If the carbon chain of the compound contains a $-\mathrm{OH}$ group, then change the ending ' $\mathrm{e}$ ' of the parent name, i.e. 'e' of butane is replaced by 'ol' (ol for alcohol).
Parent suffix: Butan-2-ol
IUPAC name: Butan-2-ol
