2 : Ester

3 : Carboxylic acid

4 : Amide

    Answer

     : CH₃CH₂CONHCH₂CH₂CH₂CH₃

     : CH₃CH₂COCH₃

     : CH₃CH₂COOH

     : HCOOCH₂CH₂CH₃
_________________
Give the main/longest chain name , functional group name and IUPAC name of the following organic compound:
CH₃CHO

Answer 1

1) Ketone : CH₃CH₂COCH₃

2) Ester : HCOOCH₂CH₂CH₃

3) Carboxylic acid : CH₃CH₂COOH

4) Amide : CH₃CH₂CONHCH₂CH₂CH₂CH₃

CH3CHO :

According to IUPAC

Root word: indicates number of carbon atoms in the longest chain = 2 carbons

Primary suffix : indicates double or triple bond presence in compound = no multiple bonds

Secondary suffix : indicates the function group present in the compound = aldehyde functional group

Primary prefix : indicates the substituents on the longest chain = no substituents

Secondary prefix : indicates the Cyclo substituent in the compound = No cyclo substituents

Hence the name is Ethanal.
