8. Which of the following compoundswould rotate a plane of polarized light? (See attachment)
9. What is the major product for the reaction shown? (See attachment)
10. Which reaction is most likely to occur by way of carbocationintermediate? (See attachment)
8. B and C would rotate a plane of polarized light.
B has a chiral centre to which four different substituents are attached: -H, -CH3, -OH and -CH2CH3.
C has two chiral centres to which four different substituents are attached: -CH3, -H, -OH …
Three multiple choice questions demonstrate how compounds rotate planes of polarized light. Also discussed are major products for reactions and reactions most likely to occur through carbocation intermediate.
