The Clemensen reduction involves the reduction of carbonyl compounds (such as aldehydes or ketones) to hydrocarbons using zinc amalgam (Zn-Hg) and hydrochloric acid (HCl).
The reaction for the reduction of a carbonyl compound, for example acetone \(( \text{CH}_3\text{COCH}_3 )\), is:
\[ \text{CH}_3\text{COCH}_3 \; \xrightarrow[\text{HCl}]{\text{Zn-Hg}} \; \text{CH}_3\text{CH}_3 + \text{H}_2\text{O} \]
Consider the following two reactions A and B: 
The numerical value of [molar mass of $x$ + molar mass of $y$] is ___.
Which one of the following graphs accurately represents the plot of partial pressure of CS₂ vs its mole fraction in a mixture of acetone and CS₂ at constant temperature?

Consider the following reaction sequence: 
Given: Compound (x) has percentage composition \(76.6%\ \text{C}\), \(6.38%\ \text{H}\) and vapour density \(=47\). Compound (y) develops a characteristic colour with neutral \(\mathrm{FeCl_3}\) solution. Identify the {INCORRECT statement.}
