D) histidine. phenylamine. Answer: 4) What is the name of this compound? CH3NCH2CH3 CH3 A) trimethylamine B) diethylamine D2 ethylmethylnitride dimethylamine

Explanation / Answer

Q1.

The Nitrogen is bonded to:

- 1 hydrogen atom

- 2 Carbons

therefore, it is a SECONDARY amine ( secondary due to two carbons bonded to it)

Q2.

This compound is

benzene aromatic ring

bromo presente

Since it has NH and CH3 this must be aniline

therefore

aniline + bromo presence in the third carbon ( counting 1 for amine, 3 for bromine)

Choose

3-bromomaniline

then

N-methyl will state that the methyl group ( CH3-) is bnded to the amine directly

so

N-methyl-3-bromoaniline will do

Q3

amino benzene, as the name implies... includes an AMINO group + benzene ring

this has the Common / IUPAC name of aniline

Q4.

This is an amine

since nitrogen is bonded to

CH3, CH3, CH2CH3

so: it has 2 methyl groups and 1 ethyl group

they must go in abc order

ethyldimethylamine
