Question

(a)
number of structural isomeric products.
(b) Number of meso forms in given structure

(c) $Me-Br+Et-Br+Pr-Br \xrightarrow [\text{dryether}]{Na}$ number of possible alkanes formed.
(d) $HCOOK\xrightarrow{\text{Kolbe ' s electrolysis}} $ moles of $H_{2}$ gas obtained after complete electrolysis.

Answer 1

(a)
Number of structural isomeric products $=3$
(b)
(c) $Me-Br+Et-Br+Pr-Br \xrightarrow[\text{dry ether}]{Na}Me-Me+Et-Et+Pr-Pr+Me-Et+Et-Pr$
(d) $HCCOK \rightarrow HCOO^{\cdot }+K^{\oplus}$
$H_{2}O\rightleftharpoons H^{\oplus}+OH^{\cdot \cdot }$
At anode $\frac{1}{2}mol$ of $H_{2}$
At cathode $\frac{1}{2}mol$ of $H_{2}$
