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)

The reaction shown below is called:
$CH_3-CHO + 4[H] \xrightarrow{Zn-Hg / \text{conc. } HCl} CH_3-CH_3 + H_2O$

Which of the following compounds gives the $2,4-DNP$ test?

The reaction of $5-$methylenecyclohex$-2-$enone with $2$ equivalents of $HBr$ yields which of the following products?

An alkene $(A)$ $C_{16}H_{16}$ on ozonolysis gives only one product $(B)$ $C_8H_8O$. $(B)$ can also be obtained by the hydrolysis of the product obtained from the reaction between cyanobenzene and $CH_3MgBr$. $(A)$ shows geometrical isomerism and decolourises $Br_2$ water. $(B)$ on treatment with $SeO_2$ produces $(C)$. Which statement is not correct about $(C)$?

Identify the product $Y$ in the following reaction: $CH_3-CO-CH_3 + 3NaOI \xrightarrow{\Delta} Y + CH_3-COONa + 2NaOH$
