Convert the following reactions by using `G.R`.
(a)

Text Solution

Verified by Experts

The product ketone contains three more `C` atoms than the starting reactant. Ketone can be obtained by the oxidation of `2^@` alcohol. So, first preapre `2^@` alcohol containing five `C` atoms. `2^@` alcohols are obtained by the reaction of aldehydes with three `C` atoms (i.e., `EtCH = O`) and `G.R` with two `C` atom `C` atoms (i.e., `EtMgbr`).

(b) The product contains two `3^@` alcoholic groups and two extra isopropyl groups at each end of the chain. This suggests that ketone reacts with `G.R` and converts the reactant into dibromo compound and then into `d-G.R`. This `di-G.R` on reaction with acetone would give the desired product.

The product is `3^@` alcohol, so acidic hydrolysis of the Grignard complex may cause dehydration. Hence, the use of of `NH_4 Cl` to decompose the complex is safer.
( c) Convert alcohol to `G.R` and then convert into amine by reacting the `G.R` with `RONH_2` followed by hydrolysis.
