Question
Write the IUPAC names of the following structural formulae:
✓
Answer
The number of carbon atoms in the longest chain: 5
Parent alkane: Pentane
Functional group:
Assign the numbering:
In the longest chain, the numbering of carbon atom starts from the carbon nearest to the functional group (both the numbering equivalent).
If the carbon chain of compound contains a
group, then change the ending of the parent name i.e. ‘e’ of pentane is replaced by ‘one’.
Parent suffix: Pentan-3-one
IUPAC name: Pentan-3-one.
Parent alkane: Pentane
Functional group:
