Primary aliphatic

WebBoth primary and secondary aliphatic amines can show a pH of 12 in the basicity test, as both types of amines are capable of accepting a proton (H+) from water to form OH- ions. However, primary amines are generally stronger bases than secondary amines because the nitrogen atom in a primary amine is attached to only one carbon atom, whereas in a … WebGiven below are two statements Statement I: Primary aliphatic amines react with H N O 2 to give unstable diazonium salts. Statement II: Primary aromatic amines react with H N O 2 to form diazonium salts which are stable even above 300 K. In the light of the above statements, choose the most appropriate answer from the options given below.
