Classify each of the molecules below. H2N — CH2 — CH3 ? 1° amine ? 2° amine ? 3° amine ? not an amine at all CH3 — CH2 — CH2 — NH2 ? 1° amine ? 2° amine ? 3° amine ? not an amine at all CH3 — NH2 ? 1° amine ? 2° amine ? 3° amine ? not an amine at all

Transcript

00:01 First of all we need to understand that how to distinguish between primary, secondary and tertiary amines.

00:07 So amines we have a nitrogen atom and nitrogen has 5 valence electron.

00:15 Two of its electron are non -bonding rest are bonding.

00:20 Okay.

00:20 Now if this nitrogen atom is attached to two hydrogen atom and consists of only one alkyl group.

00:30 Now this alkyl group apart from that we could have a ring or aromatic ring or a branched structure.

00:40 Okay.

00:40 So such like that.

00:42 Okay.

00:43 So we have a alkyl group or a aliphatic or a aromatic group here and now we have two hydrogen atoms.

00:51 So whenever we have this one alkyl group here.

00:54 Okay.

00:56 So then we say that we have one degree or primary amine.

01:01 Okay.

01:02 So this is primary amine.

01:08 Now moving on to next again nitrogen has two non -bonding electrons and this time this nitrogen atom is connected to two same or different alkyl group and rest valency is by hydrogen atom.

01:27 So whenever this happen whenever we have two same or different alkyl group then we say that we have two degree or secondary secondary amine.

01:48 Then we have nitrogen atom and again we have a lone pair of electron and this time this nitrogen atom is connected to three alkyl group they can be same or different.

02:02 Then we say that we have tertiary or three degree.

02:07 Okay.

02:09 Tertiary amine...
