EXERCISE-4

Identify A,B and C

Identify $\mathrm{A}, \mathrm{B}$ (both alkene) and $\mathrm{C}$.

Write isomeric amines of the formula ${\mathrm{C}}_3{\mathrm{H}}_9 \mathrm{N}$.

The two amines shown differ by a factor of about $40,000$ in their ionisation constants. Which is stronger base? Explain :

Why aniline does not undergo Friedel-Crafts reaction?

Two isomeric compounds $\left(\mathrm{A}\right)$ and $\left(\mathrm{B}\right)$ have ${\mathrm{C}}_4{\mathrm{H}}_{11} \mathrm{N}$ as molecular formula. Both on separately treating with ${\mathrm{HNO}}_2$ lose their ${\mathrm{N}}_2$ producing two isomeric alcohols $\left(\mathrm{C}\right)$ and $\left(\mathrm{D}\right)$ respectively of molecular formula ${\mathrm{C}}_4{\mathrm{H}}_{10}\mathrm{O}$. $\left(\mathrm{C}\right)$ reacts with Lucas reagent immediately and units oxidation. $\left(\mathrm{D}\right)$ does not reacts with Lucas reagent in cold but can be easily oxidized. Complete methylation of either $\left(\mathrm{A}\right)$ or $\left(\mathrm{B}\right)$ is made which on decomposition does not produce $1$ -butene. Identify $\mathrm{A}$ to $\mathrm{D}$.
