Consider structures I to VII and answer following the questions (I) to (II).
(i) Which of the above compounds form metamer’s pairs?
{ii) Identify the pairs of compounds which are functional group isomers.
(iii) Identify the pairs of compounds that represent position isomerism.
(iv) Identify the pairs of compounds that represent chain isomerism.
(i) V and VI or V and VII form a pair of metamers since they differ in the number of carbon atoms on their either side of the functional group, i.e., O-atom.
{ii) I and V, I and VI, I and VII; II and V, II and VI, II and VII; III and VII; III and V, II and VI; III and VII; IV and V; IV and VI and IV and VII are all functional group isomers.
(iii) I and II, III and IV and, VI and VII represent position isomerism.
(iv) I and III, I and IV, II and III and II and IV represent chain isomerism.
