(a)

Interpretation Introduction

Interpretation:

IUPAC name of given below compound has to be given.

  ${\text{CH}}_{\text{2}}\text{=O}$

Concept Introduction:

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

Aldehyde is the one of the type of organic compound with general structure of $\text{RC=OH}$.

In the nomenclature of Aldehyde, find the longest chain of the compound first then remaining groups and atoms are consider as substituent. In systematic name parent chain is ended with –al suffix.

In the nomenclature, Find the parent chin first then number the carbon atoms in the parent chain by giving lowest number caybonly carbon followed by designate the other substituent in its position in parent chain.

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

Finally the systematic name was written as, the substituent position number with prefix (di-, tri-, tetra-, ect..) of number of substituents followed by name of the substituent then write the parent chain name (which contains large number of carbon atoms in the chain).
