The sodium salt of an $\alpha-$halogen carboxylic acid,when heated with sodium nitrite followed by hydrolysis,forms:

What is the product of the pyrolysis of ethyl acetate?

In the reaction,$CH_3-COOH$ $\xrightarrow{LiAlH_4} A$ $\xrightarrow{PCl_5} B$ $\xrightarrow{Alc. KOH} C$,the product $C$ is:

Identify $C$ in the following sequence of reactions:
$2\text{-methylcyclohexanecarboxylic acid}$ $\xrightarrow{SOCl_2} A$ $\xrightarrow{NH_3} B$ $\xrightarrow{P_4O_{10}, \text{heat}} C(C_8H_{13}N)$

$CH_2=CH-CO-OCH_3$ (methyl acrylate,bp $81^\circ C$) + $CH_3-CH_2-CH_2-CH_2-OH$ (n-butyl alcohol,bp $117^\circ C$) $\xrightarrow{TsOH, \Delta} (A)$ (bp $145^\circ C$) + $CH_3OH$ (bp $65^\circ C$). Product $(A)$ of the above reaction is:

Ethyl acetate at room temperature is a
