Question

convert from alcohol to alkane by reduction process vis SN2 mechanism. (SHOW MECHANISM)

1-ethylcyclohexan-1-ol reacts with 1.TsOH, Pyridine/2.LiAlH4, H3O^+

I don't know how to describe the second one its a Phenol as the main ring with a carbon group attached to the side. It has a methyl, ethyl and alcohol attached to this carbon which is connected to the main ring.

This phenol compound with the attached alcohol, ethyl and methyl groups reacts with TsCL, Pyridine/ LiAlH4, acetone.

Obtain the suitable product for the following dehydration process of alcohol yielding alkene and ether. Also, write the mechanism for the formation alkene. (SHOW MECHANISM)

Mechanism for the formation of alkene:

2-methyl-propan-1-ol reacts with 1.H3PO4/125C

1-isopropylcyclopentanol reacts with H2SO4/190C

Assign the major product for each of the pinacol-pinacalone rearrangement. Write the mechanism for reactions A and B (i.e. for the formation of two different products).

A) 2,3-dimethyl-2,3-pentanediol reacts with H2SO4/100C

B) 1,3,4-trimethyl-1,2-cyclohexanediol reacts with H2SO4/100C

C)1,2-dimethyl-1,2-cyclopentanediol reacts with H2SO4/100C
