Answer 1

IUPAC Rules for naming ${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{NH}-{\mathrm{CH}}_3$:

• Amines are named as Alkanamines.
• The –e in the alkane name of the longest chain is changed to –amine.
• The chain is numbered to locate the amine group and substituents.
• The longest alkane chain is numbered.
• Each Alkyl group bonded to the N atom is named an N-alkyl group.
• Hence, following the above rules the IUPAC name of ${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{NH}-{\mathrm{CH}}_3$ is given by :N-Methylethanamine.

Thus, The IUPAC name of ${\mathrm{CH}}_3-{\mathrm{CH}}_2-\mathrm{NH}-{\mathrm{CH}}_3$ is N-Methylethanamine.
