An organic compound (${\text{C}}_3{\text{H}}_9\text{N}$) ($A$), when treated with nitrous acid, gave an alcohol and ${\text{N}}_2$ gas was evolved. ($A$) on warming with ${\text{CHCl}}_3$ and caustic potash gave ($C$) which on reduction gave isopropylmethylamine. Predict the structure ($A$).

Structure of a mixed oxide is cubic close-packed (c.c.p). The cubic unit cell of mixed oxide is composed of oxide ions. One fourth of the tetrahedral voids are occupied by divalent metal $A$ and the octahedral voids are occupied by a monovalent metal $B$. The formula of the oxide is:

The orbital angular momentum of a $p$ -electron is given as:
