Identify the correct statements about $Z$.
$$ \mathrm{C}_2 \mathrm{H}_5 \mathrm{NH}_2 \xrightarrow[0^{\circ} \mathrm{C}]{\mathrm{NaNO}_2 / \mathrm{HCl}} X \xrightarrow{\mathrm{H}_2 \mathrm{O}} Y \xrightarrow{\mathrm{Cu} / 573 \mathrm{~K}} Z $$
I. $Z$ is an aldehyde.
II. $Z$ undergòes Cannizzaro reaction.
III. $Z$ gives iodoform test.
IV. $Z$ does not give, test with Tollens' reagent.
Assertion (A) : Aldehydes are more reactive than ketones towards nucleophilic addition reactions
Reason (R) : In aldehydes, carbonyl carbon is less electrophilic compared to ketones.
The correct answer is
Arrange the following in the correct order of their boiling points.
What is the major product $Z$ in the given reaction sequence?
$$ \left(\mathrm{CH}_3\right)_2 \mathrm{C}=\mathrm{O} \xrightarrow[\text { (ii) } 2 \mathrm{H}_2 \mathrm{O}^{+}]{(\mathrm{i}) \mathrm{C}_2 \mathrm{H}_5 \mathrm{MgBr}} \xrightarrow[\Delta]{\substack{\text { (i) } \mathrm{OOCl}_2 \\ \text { (ii) } \mathrm{CH}_3 \mathrm{ONa}}} Y \xrightarrow[\text { Peroxide }]{\mathrm{HBr}} Z $$
