(a)

Interpretation Introduction

Interpretation: The constitution of the molecules has to be found by using their molecular formula.

Concept introduction: The arrangement of atoms that are bonded together determines its constitution and molecular formula of that particular compound.

This concept is referred as structural isomers or in more modern term constitutional isomers.

Each atom has a typical valency or valence which is defined as the ability of an atom to form a chemical bond with other atoms.  For example, carbon has four valence or tetravalent that means carbon has the capacity to form four bonds with other elements or other atoms.

Nitrogen and oxygen atoms are trivalent and divalent respectively.  Hydrogen and halogens are monovalent in nature.

To find: The constitutional isomer of the compound CH₄O.
