Concept explainers

Diol

In chemistry there are so many chemical compounds that have a hydroxyl group but a chemical compound having two hydroxyl groups (-OH) is termed as a diol. It also implies the presence of two alcohols whereas polyols contain two or more than two hydroxyl groups (-OH). Glycol or 1,2-diol is an aliphatic diol that has two alcohol groups on adjacent carbon atoms. In industries, the most commonly used diol is ethylene glycol.

Question

Wittig reactions.
H
CH3
i. Propose both pairs of the starting reactants.
ii. The above alkene can be converted to an aldehyde and a ketone. Provide a suitable reagent and
reaction condition for the conversion.
