Write the chemical reactions for the following conversions:
$1.$ Aniline to Picric acid
$2.$ Ethanal to Butan$-2-$ol
$1.$ Aniline to Picric acid
$2.$ Ethanal to Butan$-2-$ol
(N/A) $1.$ Aniline to Picric acid:
Aniline is first converted to benzene diazonium chloride using $NaNO_2$ and $HCl$ at $273-278 \ K$. This is then hydrolyzed with water to form phenol. Phenol undergoes nitration with concentrated $HNO_3$ to yield $2,4,6-$trinitrophenol,commonly known as picric acid.
$2.$ Ethanal to Butan$-2-$ol:
Ethanal reacts with ethylmagnesium bromide (a Grignard reagent) to form an addition product. Subsequent hydrolysis of this product yields butan$-2-$ol.
