Worked Solution & Example Answer:A reaction pathway to produce a primary alcohol is shown below - VCE - SSCE Chemistry - Question 1 - 2022 - Paper 1
Step 1
Identify the type of reaction that converts C₂H₄ into Compound A.
Answer
The reaction that converts C₂H₄ into Compound A is an addition reaction. In this case, HCl adds across the double bond of the ethene (C₂H₄) to form a carbocation intermediate, which then rearranges to form Compound A.
Step 2
Step 3
State the reagent(s) required to convert Compound A into a primary alcohol in the box provided.
Answer
The reagent required to convert Compound A into a primary alcohol is sodium borohydride (NaBH₄) for the reduction process, or directly using LiAlH₄ (Lithium aluminium hydride) which can also convert alkyl halides to primary alcohols.
