Fill in the table by writing the systematic name for A, B, C and D.
Explain what is meant by the term stereoisomerism.
W is an alkene with formula $\text{C}_4\text{H}_8$. On reaction with HBr it can form two carbocations, $\text{CH}_3\text{C}^+(\text{H})(\text{CH}_2\text{CH}_3)$ and $\text{H}_2\text{C}^+\text{CH}_2\text{CH}_2\text{CH}_3$. Identify W as compound A, B, C or D.
Draw the skeletal formula of the major organic product made when HBr reacts with W. Explain why this product is the major organic product.
A sample of propan-1-ol reacts with concentrated sulfuric acid to form propene. Identify the role of concentrated sulfuric acid in this reaction.
Alcohol Y reacts completely when warmed with acidified $\text{Cr}_2\text{O}_7^{2-}$ to form Z. Z is distilled from the reaction mixture as soon as it forms. Tollens’ reagent is then added to a sample of Z and warmed. A silver mirror appears. Name the type of reaction that occurs when Y is converted into Z.
Use a tick (✓) to identify the functional group(s) present in Z.
