Synthesis of Secondary and Tertiary Amines

Q.

When methyl iodide is heated with ammonia, the product obtained is

1. Methylamine

2. Dimethylamine

3. Trimethylamine

4. All of the above.

Q. Primary amines can be exclusively formed by ammonolysis of alkyl halides.

1. True
2. False

Q. What happens when ethylamine is made to react with excess formic acid and formaldehyde?

1. The intermediate is a secondary amine
2. The final product is a tertiary amine
3. This reaction is called Eschweiler-Clarke methylation
4. The mechanism involves reductive amination

Q. $\text{Butanedial}+\text{Ammonium carbonate}\stackrel{△}{\to }P$
Then:

1. P is aromatic
2. P is antiaromatic
3. P on reaction with chloroform and sodium hydroxide gives:
   
4. P on reaction with chloroform and sodium hydroxide gives:
   

Q. A hydrocarbon $A\left(C_4{H}_8\right)$ on reaction with$HCl$ gives a compound $B\left(C_4{H}_{9}Cl\right)$ which on reaction with $1$ mole of $N{H}_3$ gives a compound $C\left(C_4{H}_{11}N\right)$. On reacting with $NaN{O}_2$ and $HCl$ (low temperature) followed by treatment with water, compound $C$ yields optically active alcohol(s). Ozonolysis of $A\left(1\text{mole}\right)$ gives $2$ moles of acetaldehyde.
The compound C is:

1. Butan-2-amine
2. N, N-dimethylethanamine
3. Diethylamine
4. Butylamine
