Which of the following has a D-configuration?

Question

Quizplus · Accepted Answer

A D-configuration has the absolute configuration of (4S,5S) or (4R,5R) based on the position of the highest priority substituent on the chiral center. 
1) 11eab600_07fe_1a96_9625_55e8efe9b882_TB6688_00 has a chiral center at the 5th position with a hydroxyl group as the highest priority substituent. The stereochemistry at this center is (5R) which is the L-configuration. Therefore, this compound does not have a D-configuration.
2) 07ac7123_b3cb_69cc_383d_23e29bf687a1_TB6688_00 has a chiral center at the 4th position with the OH group as the highest priority substituent. The stereochemistry at this center is (4S) which is the D-configuration.
3) 459c4a4f_1a7b_8f06_8577_65a7157c7e45_TB6688_00 has a chiral center at the 4th position with an ethyl group as the highest priority substituent. The stereochemistry at this center is (4R) which is the D-configuration.
Therefore, only compounds 2 and 3 have a D-configuration.
