Answer 1

Answer : Major product of all the Reaction is given in the image attached

(6) Reaction = Dehydration of alcohol

First step is protonation of OH , followed by removal of H2O to generate carbocation . It will rearrange itself to most stable carbocation and then removal of H+ leads to formation of product. Major product is (A)  

(7) Correct reagent is (B)

Reaction = Oxymercuration demercuration reaction to convert alkene to alcohol .

This reaction is used when we want to attach -OH to the most substituted side of alkene carbon.

(9) Correct important intermediate is (C) .

Reaction : Reduction Reaction

Mechanism is given in the image attached. First step is attack of H- from LiAlH4 to carbonyl carbon which generate this important intermediate.

(11) Major product of this reaction is given in the image attached.

Reaction = Dehydration of alkene ( same steps as in 6 above)

Mechanism is given in the image attached
