Answer 2

Points to follow -

• Select the chain with maximum number of carbon atom along with most preferred functional group as a parent chain.
• Functional group will be given least number.

Solution -

6) Here , most preferred functional group is Amine and parent chain has 4 carbon atoms

So IUPAC name will be Butan-2-amine.

7) Here , most preferred functional group is Alkane and parent chain has 3 carbon atoms , and Bromine as substitution chain

So IUPAC name will be 2-bromopropane.

8) Here , most preferred functional group is Alcohol and parent chain has 4 carbon atoms

So IUPAC name will be Butan-2-ol.

9) Here , most preferred functional group is Amine and parent chain  has 1 carbon atoms

So IUPAC name will be Methylamine.

10) Here , most preferred functional group is Aldehyde and parent chain  has 4 carbon atoms

So IUPAC name will be Butanal or Butan-1-ol
