Question

The Fischer projection of D-erythrose is shown below.

D-Erythrose and its isomers are listed as P, Q, R, and S in Column-I. Choose the correct relationship of P, Q, R, and S with D-erythrose from Column II. Column I Column II P

1 Diastereomer Q

2 Identical R

3 Enantiomer S

(A) P arrow 2, Q arrow 3, R arrow 2, S arrow 2 (B) P arrow 3, Q arrow 1, R arrow 1, S arrow 2 (C) P arrow 2, Q arrow 1, R arrow 1, S arrow 3 (D) P arrow 2, Q arrow 3, R arrow 3, S arrow 1

Tardigrade Admin · Accepted Answer

The Fischer projections of P, Q, R and S are

P arrow 2, Q arrow 1, R arrow 1, S arrow 3

$P \to 2, Q \to 3, R \to 2, S \to 2$

$P \to 3, Q \to 1, R \to 1, S \to 2$

$P \to 2, Q \to 1, R \to 1, S \to 3$

$P \to 2, Q \to 3, R \to 3, S \to 1$

The Fischer projections of $P, Q, R$ and $S$ are

$P \to 2, Q \to 1, R \to 1, S \to 3$

Q. The Fischer projection of D-erythrose is shown below. D-Erythrose and its isomers are listed as P,Q,R, and S in Column-I. Choose the correct relationship of P,Q, R, and S with D-erythrose from Column II. Column I Column II P 1 Diastereomer Q 2 Identical R 3 Enantiomer S

P→2,Q→3,R→2,S→2

P→3,Q→1,R→1,S→2

P→2,Q→1,R→1,S→3

P→2,Q→3,R→3,S→1

The Fischer projections of P,Q,R and S are P→2,Q→1,R→1,S→3

$P \to 2, Q \to 3, R \to 2, S \to 2$

$P \to 3, Q \to 1, R \to 1, S \to 2$

$P \to 2, Q \to 1, R \to 1, S \to 3$

$P \to 2, Q \to 3, R \to 3, S \to 1$

The Fischer projections of $P, Q, R$ and $S$ are

$P \to 2, Q \to 1, R \to 1, S \to 3$
