Match the Column I Column II (i) α-Glucose and α-Galactose (a) Homologues

Question

Match the column I and column II.

	Column I		Column II
(i)	α-Glucose and α-Galactose	(a)	Homologues
(ii)	α-Glucose and α-Fructose	(b)	Epimer
(iii)	α-Glucose and α-Fructose	(c)	Anomer
(iv)	α-Ribose and α-Glucose	(d)	Functional isomers

Select the option with correct match. 

(1) (i) → (b); (ii) → (d); (iii) → (a), (iv) → (c) 

(2) (i) → (b); (ii) → (d); (iii) → (c), (iv) → (a) 

(3) (i) →(d); (ii) → (b); (iii) → (c), (iv) → (a) 

(4) (i) → (a); (ii) → (c); (iii) → (d), (iv) → (b)

Answer 1

Correct option is (2) (i) → (b); (ii) → (d); (iii) → (c), (iv) → (a) 

α-Glucose and α-Galactose are C–4 epimers 

α-Glucose is Aldohexose and α-Fructose is ketohexose hence functional isomers 

α-Glucose and β-Glucose are different in configuration at C–1 i.e. Anomeric carbon hence are anomers 

α-Ribose is pentose while α-Glucose is hexose hence homologues
