Question

bromomethane to ethanoic acid

Answer 1

                   alcoholic KOH  
C2H5Br   ------------------------------>  CH2=CH2  + HBr

                                 H3PO4                                      KMnO4
CH2=CH2  +  H2O   ------------------------->    C2H5OH    --------------------->  CH3COOH

Answer 2

Answer: The conversion is given below.

Explanation:

The above conversion is carried out in various steps:

Step 1:  Converting bromomethane to ethanenitrile.

When bromomethane is reacted with aqueous alcoholic solution of KCN, it results in the formation of ethanenitrile.

Step 2: Converting ethanenitrile to ethanoic acid.

When hydrolysis of ethaninitrile in hot acidic or alkaline medium is carried out, it leads to the formation of ethanoic acid.

The equations for the conversion is given in the image attached below.
