(a)

Interpretation Introduction

Interpretation:

Structural formula of Ethyl formate has to be drawn.

Concept introduction:

IUPAC Nomenclature:

IUAC gives rules for the naming of chemical compounds. These rules are,

Carboxylic ester is the one of the types of organic compound with general structure of $\text{RCOOR}$.

Ester contains two parts, $\text{RCO}$ is the acid part and $\text{OR}$ is the alcohol part. Parent chain must contain $\text{RCOOR}$ group.

In the nomenclature of Carboxylic ester, find the longest chain of the compound first then remaining groups and atoms are consider as substituent.

First write the alcohol part of the compound then write the acid parte with the –ate suffix.

Find the parent chin first then number the carbon atoms in the parent chain by giving lowest number Carboxylic group followed by designate the other substituent in its position in parent chain.

If more than one same substituent or Carboxylic groups were occurs, add a prefix (di-, tri-, tetra-, ect..) in front of parent chain name.

Finally the systematic name was written as, alcohol part followed acid part name with ate suffix.
