Among the isomeric amines,select the one with the lowest boiling point.

Which of the following reagents is used in the Hoffmann elimination reaction of amines?

$(A)$ $\xrightarrow[(1) \text{ excess } CH_3I/K_2CO_3, (2) \text{ } Ag_2O/H_2O, (3) \text{ } \Delta]{} (B)$ $\xrightarrow[(i) \text{ excess } CH_3I/K_2CO_3, (ii) \text{ } Ag_2O, (iii) \text{ } \Delta]{} H_2C=CH-CH(CH_3)-CH=CH_2$. Identify $(A)$.

$A$ compound with molecular mass $180$ is acylated with $CH_3COCl$ to get a compound with molecular mass $390$. The number of amino groups present per molecule of the former compound is:

In the given carbylamine reaction,the value of $x$ (moles of $KOH$ consumed) is:
$C_6H_5NH_2 + CHCl_3 + xKOH \rightarrow C_6H_5NC + 3KCl + 3H_2O$

Which statements are True? $A$. In Hoffmann bromamide degradation,$4$ moles of $NaOH$ and $1$ mole of $Br_{2}$ are consumed per mole of an amide. $B$. Hoffmann bromamide reaction is not given by alkyl amides. $C$. Primary amines can be synthesized by Hoffmann bromamide degradation. $D$. Secondary amide on reaction with $Br_{2}$ and $NaOH$ will give secondary amine. $E$. The by-products of Hoffmann degradation are $Na_{2}CO_{3}$,$NaBr$ and $H_{2}O$. Choose the correct answer from the options given below:
