Formation of Diazonium Salts

Q.

Assertion (A): Both aromatic and aliphatic primary amines produce stable diazonium salts on diazotization

Reason (R): Aromatic diazonium salt exhibit resonance

1. A and R are true and R is the correct explanation of A

2. A and R are true and R is not the correct explanation of A

3. A is true, R is false

4. A is false, R is true

Q. What is the product when aniline reacts with $HCl,NaN{O}_2$ at 0 - 5 ${}^{\circ }C$?

1. 
2. 
3. 
4. 

Q. The major product obtained when N-methylaniine is treated with $NaN{O}_2$ and $HCl$ at 0 - 5 ${}^{\circ }C$ is:

1. 
2.

Q. $C_{13}{H}_{10}O\stackrel{C{F}_{3}C{O}_{3}H}{\to }\left(A\right)\stackrel{H_3{O}^{+}}{\to }B+C$

With neutral $FeC{l}_3,C$ gives violet colour. B on decarboxylation and C on reduction with zinc dust, gives same compound. The correct statement is:

1. C gives dye test positive in weakly alkaline medium
2. C gives dye test positive in weakly acidic medium
3. C gives dye test positive in strongly alkaline medium
4. B can be formed by oxidation of toluene with chromyl chloride
