MHT CET Chemistry Question (2026) — Solution

Step-by-step solution

The given molecule is 3-methylbutan-1-ol, with the expanded structural formula HO - CH _2- CH _2- CH ( CH _3)- CH _3. In this structure, every carbon atom is bonded to four other atoms (either carbon, hydrogen, or oxygen) entirely through single ( ) bonds. Since there are no bonds present, all the carbon atoms are sp^3 hybridized. Counting the carbon atoms: Two - CH _2- groups 2 carbon atoms One - CH - group 1 carbon atom Two - CH _3 groups 2 carbon atoms Total number of sp^3 hybridized carbon atoms = 2 + 1 + 2 = 5.
