ALDEHYDES, KETONES AND CARBOXYLIC ACID
28291
Amines are basic in nature because:
1 They produce \(OH^-\) ions when treated with water
2 They have replaceable \(H\) atoms on \(N\) atoms
3 They have lone pair of electron on \(N\) atom
4 None of these

Which of the following diazonium salt is relatively stable of \(0-5\,^o C\) :
1 \(CH_3-N\equiv N\}^{\oplus} Cl^-\)
2 \(CH_3C(CH_3)-N\equiv N\}^{\oplus} Cl^-\)
3 \(C_6H_5-N\equiv N\}^{\oplus} Cl^-\)
4 \((CH_3)_3C-N\equiv N\}^{\oplus} Cl^-\)
Explanation:
Diazonium salts obtained from aliphatic primary amines are unstable. Those obtained from aromatic primary amines are relatively stable. Benzene diazonium chloride \(\left( C _6 H _5- N \equiv N ^{\oplus} Cl ^{-}\right)\)is obtained from aromatic primary amine. Hence, it is relatively stable.

Alkylamine dissolve in hydrochloric acid to form alkylammonium chloride. The nitrogen in the latter salt is:
1 Quadricovalent only
2 Tricovalent only
3 Unielectrovalent only
4 Quadricovalent, Unielectrovalent
Explanation:
Alkylamine dissolve in hydrochloric acid to form alkylammonium chloride. The nitrogen in the latter salt is quadricovalent, unielectrovalent. Quadricovalent means that nitrogen can form \(4\) covalent bonds. Unielectrovalent means that nitrogen forms a singly charged ion.

28294
Which of the following can be detected by carbylamine reaction :
1 They produce \(OH^-\) ions when treated with water
2 They have replaceable \(H\) atoms on \(N\) atoms
3 They have lone pair of electron on \(N\) atom
4 None of these
