L-isomer of tetrose X(C4H8O4)X ( {C}_{4}{H}_{8}{O}_{4} ) gives positive Schiff’s test and has two chiral carbons. On acetylation ‘X’ yields triacetate. ‘X’ also undergoes following reactions.

L-isomer of tetrose X ( C _ 4 H _ 8 O _ 4 ) gives positive Schiff’s test and has two chiral carbons. On

Options

  1. AWhat is the ratio of wave number of first line (lowest energy line) of Balmer series of H atomic spectrum to first line
  2. BWhat is the ratio of wave number of first line (lowest energy line) of Balmer series of H atomic spectrum to first line
  3. CWhat is the ratio of wave number of first line (lowest energy line) of Balmer series of H atomic spectrum to first line
  4. DWhat is the ratio of wave number of first line (lowest energy line) of Balmer series of H atomic spectrum to first line

Correct answer

B. What is the ratio of wave number of first line (lowest energy line) of Balmer series of H atomic spectrum to first line

Step-by-step solution

The tetrose is giving Schiff's test means it has aldehyde group. The compound XX on reduction with NaBH4{NaBH}_{4} give Chiral compound so compound can be identified as L-isomer of tetrose X ( C _ 4 H _ 8 O _ 4 ) gives positive Schiff’s test and has two chiral carbons. On. The compound can give triacetate on acetylation.

L-isomer of tetrose X ( C _ 4 H _ 8 O _ 4 ) gives positive Schiff’s test and has two chiral carbons. On

L-isomer of tetrose X ( C _ 4 H _ 8 O _ 4 ) gives positive Schiff’s test and has two chiral carbons. On
