Step 3: If excess alcohol is present in the hemiacetal, the hemiacetal can be further converted to an acetal product, but only in the presence of acid. R₁ R2 R3OH, H+ HO R₁ X OR3 R3OH, H+ R30 OR3 + H₂O R₁ R₂ R₂ acetal hemiacetal Why is acid required? The alkoxy group in the hemiacetal must first be converted into a good leaving group. Acid stabilizes the product. Acid stabilizes the hemiacetal, making it more reactive. The hydroxy group in the hemiacetal must first be converted into a good leaving group.

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.
