Answer 1

Answer: The answers to all three given questions are as the below stated

Explanation:

1. To identify anionic radical in the inorganic salt M3, the dry and wet test can be used. In the dry test, a small amount of the salt M3 is heated in a dry test tube, and the gas evolved is tested with damp litmus paper. If the litmus paper turns red, it indicates the presence of a hydroxide ion (OH-) in the salt M3. In the wet test, a small amount of the salt M3 is dissolved in water, and a few drops of dilute hydrochloric acid (HCl) are added to the solution. If a white precipitate forms, it indicates the presence of a chloride ion (Cl-) in the salt M3.
2. To identify functional groups in the given unknown organic compound 'L', several tests can be used. One way to identify a functional group is to treat a small amount of the unknown compound 'L' with a specific reagent and observe the reaction. For example, if a few drops of bromine water are added to a solution of the unknown compound 'L' in ethanol, and the bromine water turns colorless, it indicates the presence of a double bond in the compound 'L' (C=C) unsaturated hydrocarbon.

3. Benzoic acid can be prepared from benzaldehyde through oxidation. The oxidation can be performed by the Jones reagent (chromium trioxide in sulfuric acid). The reaction between benzaldehyde and the Jones reagent will produce benzoic acid, which can then be isolated and purified by recrystallization.

benzaldehyde +Jones reagent (CrO3 + H2SO4) ------> Benzoic acid
