$\left(1\right)$ To prepare ethanol, ${\mathrm{CH}}_3\mathrm{Mgl}$ is treated with the other reagent $\mathrm{HCHO}.$

$\left(2\right)$ Urotropine is formed by the action of $\mathrm{HCHO}$ with ${\mathrm{NH}}_3.$

$\left(3\right)$ The conversion of acid chlorides into aldehydes by reduction is termed Rosenmund's reduction.

$\left(4\right)$ Aldehyde show reducing properties due to their ready conversion into ketons.

Which of the following statement is/are correct.

$\left(1\right)$ Hydrazone of an aldehyde when heated with sodium ethoxide forms alkane This is known as wolf-kishner reaction.

$\left(2\right)$ Cannizzaro's reaction is given by those aldehydes which do not have $\alpha$-hydrogen atom.

$\left(3\right)$ Two separate solutions, Fehling's solution $\mathrm{A}\left({\mathrm{CuSO}}_4\right)$ and Fehling's solution $\mathrm{B}(\mathrm{NaOH}+$ roschell salt are at first mixed up together and is then heated with the aldehyde. A $\mathrm{CuO}$ precipitate is formed.
