Draw the structures of each of the amines. mark as primary, secondary or tertiary.
a) cyclohexylamine
b) 1-methylbutylamine
c) n, n-dimethylaniline
d) n-methylethylamine

A. Primary.

B. Primary.

C. Tertiary

D. Secondary

Explanation:

Amines are derivatives of ammonia, wherein one or more hydrogen atoms have been replaced by a substituent such as an alkyl or aryl group. A primary amine has one alkyl (or aryl) group on the nitrogen atom, a secondary amine has two, and a tertiary amine has three.

The structures are in the image.

A. As the structure has just one alkyl group, the amine is PRIMARY

B. As the structure has just one alkyl group, the amine is PRIMARY

C. As the structure has two alkyl and one aryl groups, the amine is TERTIARY

D. As the structure has two alkyl groups, the amine is SECONDARY.

step-by-step explanation:

  the   balanced   equation   for   reaction of   ca metal   with   o2 to   produce   cao   is as below

2 ca+ o2→ 2 cao2

  explanation

the reaction is   balanced     since the   number of atoms   in reactant side is   equal to   number of atoms   in   product side.   for   example   they   are 2   atom of   ca in   reactant   side   and   2   atoms of ca   in   the product side.

  the   process   is a   meet the   requirement   of   redox   reaction because :     calcium   is   oxidized   from   oxidation state 0   to 2+   while   oxygen   is reduced from   oxidation   state   0   to 2-
