The configuration of the chiral centre and the geometry of the double bond in the following molecule can be described by

A)  R and E         

B)  S and E

C)  R and Z         

D)  S and Z

Correct Answer: C

Solution :

Since priority sequence is left to right, therefore compound will exhibit configuration. Since both heavier and lighter groups are on the same side wrt C = C bond, therefore compound will show Z-configuration.
