- Provide the reagents and solvents (where appropriate) needed to bring about the following transformations. (a) CI (b)arrow_forward(a) When bromine is added to two beakers, one containing phenyl iso propyl ether and the other containing cyclohexene, the bromine color in both beakers disappears. What observation could you make while performing this test that would allow you to distinguish the alkene from the aryl ether? (b) Write any three methods in detail for the preparation of aldehyde from primary alcohol. (c) State the clemmenson reduction.arrow_forward(a) Cyclohexa-1,3-diene can be converted into a tetrasubstituted haloalkane when reacted with bromine in ether.
