MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The chemical formula of glycerol is CH_2(OH)-CH(OH)-CH_2(OH). The principal functional group is the hydroxyl group (-OH), which is indicated by the suffix 'ol'. The longest carbon chain containing the -OH groups has 3 carbon atoms, so the parent alkane is propane. Numbering the carbon chain from either end gives the positions of the -OH groups as 1, 2, and 3. Since there are three hydroxyl groups, the multiplier 'tri' is used. Combining these parts, the IUPAC name of glycerol is propane-1,2,3-triol. Answer: Propane - 1,2,3-triol.
