1 Tautomers
2 Metamers
3 Position isomers
4 Funcitonal group isomers
Explanation:
\(\mathop {{\text{C}}{{\text{H}}_3} - {\text{C}}{{\text{H}}_2} - {\text{O}} - {\text{C}}{{\text{H}}_2} - {\text{C}}{{\text{H}}_3}}\limits_{{\text{Methoxyethane}}} \) and \(\mathop {{\text{C}}{{\text{H}}_3} - {\text{O}} - {\text{C}}{{\text{H}}_2} - {\text{C}}{{\text{H}}_2} - {\text{C}}{{\text{H}}_3}}\limits_{{\text{Propan - 1 - ol}}} \) are metamers of each other. (Same functional group but different nature of alkyl groups attached to functional group).

Number of racemic mixture(s) obtained by optical isomers of \(4 - {\text{chloro}}\, - 2,3 - {\text{dihydroxy}}\) pentanal is ____.
1 1
2 2
3 4
4 5
Explanation:
No. of optical isomers \( = {2^{\text{n}}} = {2^3} = 8\) \(({\text{n}} = 3\) chiral carbons) No.of racemic mixtures \( = 8/2 = 4\) So, the correct option is (3).
