Question

L-isomer of tetrose X (\(C_4H_8O_4\)) gives positive Schiff’s test and has two chiral carbons. On acetylation, ‘X’ yields triacetate. ‘X’ undergoes following reactions

Chiral compound ‘X’ is

• A.

  

• B.

  

• C.

  

• D.

  

Hint:

For carbohydrates, reactions such as Schiff’s test and acetylation help identify the presence of aldehyde groups and determine the stereochemistry of the compound.

Answer 1

The Correct Option is D

The reaction of L-tetrose with HNO\(_3\) results in the formation of a compound with two chiral centers, and on reduction with NaBH\(_4\), a compound (B) is formed which is optically active.
