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.


#2

(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.
