`CH_(3)NH_(2)+CHCl_(3)+KOH to` nitrogen containing compound `+KCl+H_(2)O`. Nitrogen containing compound is

Options

A. `CH_(3) - C -= N`
B. `CH_(3) - NH - CH_(3)`
C. `CH_(3) - overset(theta)(N) -= overset(o+)(C)`
D. `CH_(3) overset(o+)(N) -= overset(theta)(C)`

Answer

`d`

Explanation

`CH_(3)NH_(2) + CHCl_(3) + 3KOH rarr CH_(3)NC + 3KCl + 3H_(2)O`
`CH_(3)NC` or `CH_(5) overset(o+)(N) -= overset(theta)(C)` Methyl isocyanide
or methyl carbylamine
This reaction is an example of carbylamine reaction and it is used for the distinction of `I^(@)` aminers from `2^(@)` and `3^(@)` amines or identification of `p-` amino group.
