write the IUPAC names plz​

Answer 1

Please learn to do your homework yourself then only you will understand it, please don't ask your homework questions on brainly from next time it is very bad to copy and cheat.

I am helping you this time but remember to understand and do it from next time onwards.

a)  The Nitrogen atom is attached to three other carbons, so it is a tertiary amine.

The IUPAC name of it will be: Ethylmethylpropylamine

b) The nitrogen atom is attached to one other carbon atom, so it is a primary amine.

=>You will start numbering the longest carbon chain from the nitrogen side of the molecule.

=>Longest carbon chain is 4 carbon atoms or Butane.

=>Both Methyl groups are attached to the third carbon atom.

=>Amine group is attached to 1st carbon atom.

So, IUPAC name will be:  3,3-Dimethyl-1-butanamine

c) The Nitrogen atom is attached to two other carbon atoms, so it is a secondary amine.

=>The two groups attached to the nitrogen are, Ethyl and isopropyl.

So, the IUPAC name of the amine will be:

Ethylisopropylamine           OR           Ethyl-1-methylethylamine
