A secondary amine is a compound which possesses .

Options

A. one - `NH_(2)` group bonded to the second carbon of the main carbon chain
B. one`-NH_(2)` group boned to a secondary carbon atom
C. one-NH-group bonded to two alky1 or ary1 groups
D. two`NH_(2)` groups

Answer

C

Explanation

Amines are classified as primary `(1^(@))` secondary `(2^(@))` and tertiary `(3^(@))` depending upon the number of hydrogen atoms substituted by alky1 or ary1 groups in ammonia molecule If two hydrogen atoms of ammonia or one hydrogen atom of `1^(@)` amine are substituted by another alky1/ary1 group we get `2^(@)` amine
`R - NH -R' R -R-NH -Ar-NH-Ar'` .
