Question

Write the IUPAC names of the following structural formula.

CH₃ – CHOH – CH₃

Answer 1

The number of carbon atoms in the longest chain: 3

Parent alkane: Propane

Functional group: -OH (Ol)

Assign the number: 2

The carbon atom to which the -OH group is attached is numbered as C₂.

If the carbon chain of the compound contains a -OH group then change the ending of the parent name, i.e., ‘e’ of propane is replaced by ‘Ol’. (ol stands for alcohol)

Parent suffix: Propan-2-Ol

IUPAC name: Propan-2-Ol
