Choose the most appropriate reagent(s) for conversion of 2-phenylethanol to (2-bromoethyl)-benzene. hbr, h2o nabr, acetone br2 pbr3 br2, roor

is the most appropriate reagent

Explanation:

is the most appropriate reagent for the given conversion.

Because in presence of , -OH group is replaced by Br without any arrangement of the alcohol substrate.

Here -OH groups first attacks and replaces a from it. This gives a nucleophilic substitution reaction in the second step to break C-O bond and to form C-Br bond.

Full mechanism has been shown below.

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.

add 2 molecules of hydrogen peroxide and 2 molecules of water. since oxygen is naturally diatomic, the total number of atoms of each element is now the same on both sides of the equation so it is balanced.

this may not be entirely correct but let me know.
