Write any two methods for the preparation of Ketones.

Explanation

a) `H_(3)C-C-=CH+H_(2)O underset(HgSO_(4))overset(H_(2)SO_(4))to CH_(3)-underset(OH)underset(|)C=CH_(2)hArr underset("Acetone")(CH_(3)-underset(O)underset(||)C-CH_(3))`
b) `2R-MgX+CdI_(2) to R_(2)Cd+2MgXI`
`2R^(1)-underset(O)underset(||)C+Cl + R_(2)Cd to 2R^(1) -underset(O)underset(||)C-R+CdCl_(2)`
Acyl chlorides react with dialkyl cadmium give ketones.
