Formed product will give

(1)  Ceric ammonium nitrate and ${\mathrm{NaHCO}}_3$ test

(2)  ${\mathrm{NaHCO}}_3$ test and DNP test

(3)  ${\mathrm{NaHCO}}_3$ and Victor Meyer test

(4)  Both (A) & (C)

The incorrect method for the preparation of Me₃COMe in good yield is

1. Me₃CCl + MeONa →

2. \(Me_{2}C=CH_{2}\xrightarrow[(ii)NaBH_{4}]{(i) Hg(OAc)_{2}/MeOH}\)

3. Me_3CONa + MeCl ⟶

4. \(Me_{2}C=CH_{2}\xrightarrow[MeOH]{H^{+}}\)

 Product of products

1.  R - COOH only

2.  R - CHO only

3.  R - CHO and R - COOH

4.  $O O$
$\left|\right| \left|\right|$
$R -C - C - R$

$\mathrm{PH} - \mathrm{CHO} \underset{{\mathrm{CH}}_3\mathrm{COONa}/{\mathrm{H}}_2\mathrm{O}}{\overset{{\left({\mathrm{CH}}_3 - \mathrm{CO}\right)}_2\mathrm{O}}{\to }}\left(\mathrm{A}\right)$
$\mathrm{The} \mathrm{prodct} \mathrm{A} \mathrm{is}$
