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.
