Solution
(ii) Cyclohexanone into cyclohexane
(iv) Benzophenone into diphenyl methane
Explanation:
The carbonyl group of aldehydes and ketones is reduced to \[\ce{CH2}\] group on treatment with zinc amalgam and concentrated hydrochloric acid (Clemmensen reduction) and the corresponding alkane is formed.
