Which is the most suitable reagent for the following transformation?
$CH_3-CH=CH-CH_2-CH(OH)-CH_3 \rightarrow CH_3-CH=CH-CH_2-COOH$

Which among the following compounds has the highest boiling point?

In the following sequence of reactions,$CH_3-Br$ $\xrightarrow{KCN} A$ $\xrightarrow{H_3O^{+}} B$ $\xrightarrow[ether]{LiAlH_4} C$,the end product $(C)$ is:

Assertion: $CH_3COCl$ is converted to $CH_3CONH_2$ on reaction with $NH_3$.
Reason: $Cl^{-}$ is a stronger nucleophile and better leaving group.
