ALDEHYDES, KETONES AND CARBOXYLIC ACID

28071 Urea can be tested by

1 Benedict test

2 Mullicken test

3 Ninhydrin

4 Biuret test

Explanation:

Biuset is a compound formed by heating urea at $1800$ which results in the condensation of $2$ molecules of urea. The peptide bands in Biusect give a positive result for the test hence, the reagent is named so:. It is considerred as a general test for compounds (proteins and petites) having two or more peptide $(C o - N H)$ bonds.

28073 Reaction between an acid and alcohol will give

1 Higher

C

containing acid

2 Secondary alcohol

3 Alkane

4 Ester

Explanation:

Acids react with alchols give ester, this process is known as estesification. $R C O O H + R^{'} O H ⟶ R C O O R^{'}$
