How do you write the IUPAC name of a given organic compound?

Solution

A complete IUPAC name of an organic compound may be represented as:
Prefix + Word root + Primary suffix + Secondary suffix
For example, the complete IUPAC name of the compound

(i) Prefix: Bromo
(ii) Word root: Pent
(iii) Primary suffix: yne
(iv) Secondary suffix: oic acid
∴ Complete name of the compound is 4- Bromopent-2 yne-1-oic acid.
Here 4, 2 and 1 represent the positions of prefix, primary suffix and of the secondary suffix in the carbon atom chain.
