Chemical Science Exams Question – CUET PG 2013
The configurations at the two stereocentres in the compound given below are: (a) 1R,4R (b) 1R,4S (c) 1S,4R (d) 1S,4S Correct Answer: (a) 1R,4R Explanation: The configuration at both stereocentres is determined using CIP priority rules. After orienting the lowest priority group away from the observer, both centres show clockwise arrangement, hence R-configuration.
