When ethanal reacts with $CH_3MgBr$ and $C_2H_5OH$/dry $HCl$,the products formed are

Which of the following gives an alcohol and salt of carboxylic acid when reacted with conc. $NaOH$?

The reaction of $A$ to give $B$ and $C$ as shown in the reaction scheme is an example of:
$CH_2=CH_2$ $\xrightarrow[2. Zn/H_2O]{1. O_3} A$ $\xrightarrow{Conc. NaOH} B + C$
(Where $B$ is an alcohol and $C$ is a sodium salt of a carboxylic acid)

An organic compound '$X$' having molecular formula $C_5H_{10}O$ yields phenylhydrazone and gives negative response to the iodoform test and Tollens' test. It produces $n-$pentane on reduction. '$X$' could be

Amongst the following compounds, the one that will not respond to Cannizzaro reaction upon treatment with alkali is

In the following sequence of reactions,the final product $D$ is:
