Explanation: The addition of water to acetylene produces acetaldehyde.

Explanation: Cellulose is hydrolysed to glucose by acids and to cellobiose by its own specific enzyme cellulase.

Explanation: Enzymes and dilute acids hydrolyse starch ii1to maltose and glucose, whereas inulin yields only fructose by this treatment.

Explanation: Organic esters of all kinds, including the esters of carbohydrates, are quite subject to hydrolysis with acids, bases, and, in many cases, enzymes.

Explanation: Hydrolysis of esters is reversible, unlike that of the carbohydrates, so that the equilibrium point may be approached from both sides.

Explanation: The esters of inorganic acids, ethyl and methyl sulphates, ethyl hydrogen: sulphate, the alkyl phosphates, glyceryl nitrate, etc., may all be hydrolysed, generally speaking, by acids and bases.

Explanation: The acid halides, like acetyl chloride, reacting readily with water alone, whereas varying degrees of resistance are shown by the alkyl and aryl compounds.

Explanation: The aromatic halides are much more difficult to hydrolyse, acids on the other hand are easy to hydrolyse.

Explanation: Aliphatic and aromatic amines-ethylamine and aniline-resist hydrolysis even under extreme conditions, though the production of a-naphthol from a-naphthyl amine under pressure is recorded.

Explanation: Benzene sulfonic acid, when treated with steam under pressure, yields benzene and sulfuric acid.
