Most Important Selected Qs for JEE AdvancedChemistryBiomolecules
Among the following statements about the molecules X and Y , the one(s) which correct is (are)
Options
- AX and Y are diastereomers
- BX and Y are enantiomers
- CX and Y are both aldohexoses
- DX is a D-sugar and Y is an L-sugar
Correct answer
D. X is a D-sugar and Y is an L-sugar
Step-by-step solution
Both the given molecules contain 6 carbon atoms with an aldehyde group, so these are called aldohexoser, In X , the -O H attached to second last carbon in on right hand side while in Y it is on left hand side, so x_ i j D-sugar and Y is L-sugar, X and Y are the mirror images of each other, i.e., these are enantiomers.
