If -x2212-OH group is on the right-hand side to the last carbon with respect to the highest oxidised carbon at the top- it is called D-isomer and if it is on the left side- it is called L-isomer-xA0-So- the names of the compounds are D-erythrose- D-threose- L-erythrose- L-threose- respectively-

If −OH group is on the right-hand side to the last carbon with respect to the highest oxidised carbon at the top, it is called D-isomer and if it is on the left side, it is called L-isomer. So, the names of the compounds are D-erythrose, D-threose, L-erythrose, L-threose, respectively.

L-erythrose, L-threose, D-erythrose, D-threose
D-erythrose, D-threose, L-erythrose, L-threose
L-erythrose, L-threose, L-erythrose, D-threose
D-threose, D-erythrose, L-threose, L-erythrose

If $- O H$ group is on the right-hand side to the last carbon with respect to the highest oxidised carbon at the top, it is called D-isomer and if it is on the left side, it is called L-isomer.

So, the names of the compounds are D-erythrose, D-threose, L-erythrose, L-threose, respectively.
