Answer 1

The right answer for the question that is being asked and shown above is that: "C) CH3CH2MgBr, ether; then KMnO4, OH2 ; then H3O+; then Br2, FeBr3."

These are the following choices:
A) Br2, FeBr3; then KMnO4, OH2 ; then H3O+
B) KMnO4, OH2 ; then H3O+; then Br2, FeBr3
C) CH3CH2MgBr, ether; then KMnO4, OH2 ; then H3O+; then Br2, FeBr3
D) CH3CH2Br, AlCl3; then Br2, FeBr3; then KMnO4, OH2 ; then H3O+
