i need help answering these thank you Problem IV The Elimination reaction allows the removal from a molecule of a Leaving group and a neighboring Hydrogen to generate a double bond. When that reaction is performed on a cyclohexane, the leaving group (or in the example below, and the must be Axial as shown below. When the reaction is performed on the two molecule below (A and B), it is found that the reaction works very well on molecule A...
