Write the major products in the following: (i) [273-283 K]HNO 3 + H 2SO 4 (ii) + NaOH [Δ]CaO (iii) NH 2OH OR (i) Oxidation of propanal is easier than…

(a) (i) / m-Nitrobenzaldehyde (ii) / Cyclohexane (iii) / Ethanal oxime OR (b) (i) Because oxidation of propanal involves cleavage of a C–H bond, which is weaker than the C–C bond of propanone. (ii) On heating with NaOH and I 2, acetophenone gives a yellow precipitate of iodoform whereas benzophenone does not. (iii)

(a)
Write the major products in the following :
(i)
$\displaystyle \xrightarrow[273-283\ \text{K}]{\mathrm{HNO_3 + H_2SO_4}}$
(ii)
$\displaystyle +\ \mathrm{NaOH} \xrightarrow[\Delta]{\mathrm{CaO}}$
(iii)
$\displaystyle \xrightarrow{\mathrm{NH_2OH}}$
OR(b) (i) Oxidation of propanal is easier than propanone. Why?
(ii)
How can you distinguish between Acetophenone and Benzophenone?
(iii)
