Question

A Fischer projection of 1-deuterioethanol, CH3-CHD-OH, shows the vertical chain, top to bottom: CH3, C1, D. On C1 the left group is OH and the right group is H. Using CIP rules (mass number decides between isotopes), the configuration of C1 is

Accepted Answer

S

Answer

R

Answer

not a stereocentre

Answer

R, because D and H are identical in priority

A Fischer projection of 1-deuterioethanol, $CH X_{3} - CHD - OH$ , shows the vertical chain, top to bottom: $CH X_{3}$ , C1, $D$ . On C1 the left group is $OH$ and the right group is $H$ . Using CIP rules (mass number decides between isotopes), the configuration of C1 is
