Among the following statements about the molecules X and Y , the one(s) which correct is (are)

Options

  1. AX and Y are diastereomers
  2. BX and Y are enantiomers
  3. CX and Y are both aldohexoses
  4. 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.
