- The product formed when 2-methylpropene is treated with HBr is: (A) 2-bromo-2-methylpropane (B) 1-bromo-2-methylpropane (C) 2-bromo-1-methylpropane (D) 1-bromo-1-methylpropane (A)
The product formed when 2-methylpropene is treated with HBr is 2-bromo-2-methylpropane. This is because the reaction proceeds via a carbocation intermediate, which is stabilized by the methyl groups.
- Which of the following will give iodoform test? (A) Ethanol (B) Ethane (C) Propanol (D) 2-propanol (D)
2-propanol will give iodoform test because it contains a methyl group attached to a carbonyl group. The methyl group is oxidized to an aldehyde, which is then iodinated to form iodoform.
