Match the compounds with their IUPAC name.

• A. N-methylethanamine
• B. Hexane-1,6-diamine
• C. Propan-2-amine
• D. 2-Methylaniline

Answer 1

The structure of hexamethylenediamine is ${\mathrm{NH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{CH}}_2{\mathrm{NH}}_{2.}$
On numbering, the carbons attached to NH₂ will get 1st and 6th positions.
The structure of methylethylamine is ${\mathrm{CH}}_3{\mathrm{NHCH}}_2{\mathrm{CH}}_{3.}$
o-Toluidine is aniline with a methyl group at the second position of the ring.
Isopropylamine is a propane chain with amino group at the second position.
