MCQ
The following carbohydrate is
  • A
    a ketohexose
  • ✓
    an aldohexose
  • C
    an $\alpha$-furanose
  • D
    an $\alpha$-pyranose
✓

Answer

Correct option: B.
an aldohexose
b
It is a $\beta$-pyranose (since $OH$ group is above at anomeric carbon) hence, it is an aldohexose.

If one of the group on anomeric carbon is $- CH _2 OH$ then it is ketohexose.

Option $B$ is correct.
