Answer
The type of reaction that converts C₂H₆ (ethane) into Compound A is an addition reaction. In this process, the hydrogen chloride (HCl) adds to the ethane, leading to the formation of a haloalkane (alkyl halide), specifically an ethyl halide.
Step 2
Write the semi-structural formula for Compound B.

Answer
The semi-structural formula for Compound B, which is an isomer of Compound A, can be represented as:
CH₃-CH(CH₃)-Cl
This indicates a branched alkyl halide structure.

Answer
To convert Compound A into a primary alcohol, the reagent required is sodium hydroxide (NaOH) in an aqueous solution. This reaction typically involves a hydrolysis or substitution process that replaces the halogen in Compound A with a hydroxyl group (-OH), resulting in a primary alcohol.
