Question

What are halogens, ketones, alcohol, aldehydes, carboxylic acid ?

Answer 1

1)HALOGEN,
any of the elements fluorine, chlorine, bromine, iodine, and astatine, occupying Group 17 of the periodic table. They are reactive non-metallic elements which form strongly acidic compounds with hydrogen from which simple salts can be made.

2)ketones
an organic compound containing a carbonyl group =C=O bonded to two hydrocarbon groups, made by oxidizing secondary alcohols. The simplest such compound is acetone.

3)Alcohol
any organic compound whose molecule contains one or more hydroxyl (OH) groups attached to a carbon atom.

4)aldehydes
an organic compound containing the group —CHO, formed by the oxidation of alcohols. Typical aldehydes include methanal (formaldehyde) and ethanal (acetaldehyde).

5)Carboxylic acid
A carboxylic acid is an organic compound that contains a carboxyl group. The general formula of a carboxylic acid is R–COOH, with R referring to the rest of the molecule. Carboxylic acids occur widely and include the amino acids and acetic acid. Salts and esters of carboxylic acids are called carboxylates.
