How would you distinguish experimentally between alcohol and carboxylic acid?

Alcohol and a carboxylic acid can be experimentally distinguished by the sodium bicarbonate test. When carboxylic acid reacts with sodium bicarbonate solution, carbon dioxide is evolved with a brisk effervescence along sodium acetate is formed. RCOOH + NaHCO 3 → RCOONa + H 2 O + CO 2 ↑ Brisk efferevescence

What are structural isomers? Write two structures of butane molecules.

Structural isomers are isomers that have the same component atoms but are arranged differently from each other are called structural isomers. Butane has two structural isomers, butane and isobutane. The structures are as follows:

Can detergent be used to test the hardness of water? Give reason.

Detergents are ammonium or sulphonate salts of long-chain carboxylic acids. Detergent can not be used to test the hardness of the water. Because soap form lather with soft water only. Detergent forms lather with both hard and soft water both.
