Question
Given below are two statements:
Statement-I : 
and 
are two anomers of D-(+)-glucose.
Statement-II : The open chain forms of D-glucose and D-fructose contain three similar chiral carbons at $C_{3},C_{4}$ and $C_{5}$.
In the light of the above statements, choose the correct answer from the options given below:
Options
A.Both Statement-I and Statement-II are true.
B.Both Statement-I and Statement-II are false.
C.Statement-I is true but Statement-II is false.
D.Statement-I is false but Statement-II is true.
Solution
Sol. [Key Concept: The two ring structures differ only at the anomeric $C_{1}$ ($\alpha$- and $\beta$-D-glucose); glucose and fructose share identical configurations at $C_{3},C_{4},C_{5}$.]
α-D-Glucose and β-D-Glucose are anomers.
At C-3, C-4 and C-5 are identical configuration in glucose and fructose.
