(iodoform, acetaldehyde, positive, greater, acidic, acetone, disaccharide, negative, increases, glucose, decreases, chloroform, polysaccharide, lactose, lesser, basic, cationic hydrolysis, anionic hydrolysis)
(i) Calcium acetate on heating gives _________ which gives _________ on heating with iodine and sodium hydroxide solution.
(ii) On dilution of a solution, its specific conductance __________ while its equivalent conductance ___________.
(iii) Sucrose is a __________ and yields upon hydrolysis, a mixture of ________ and fructose.
(iv) More __________ the standard reduction potential of a substance, the ___________ is its ability to displace hydrogen from acids.
(v) An aqueous solution of $C{H}_{3}COONa$ is __________ due to _________.

Answer 1

(i) Calcium acetate on heating gives $acetone$ which gives $iodoform$ on heating with iodine and sodium hydroxide solution.
$(C{H}_{3}COO{)}_{2}Ca\underset{\text{Dry distillation}}{\overset{\Delta }{\to }}C{H}_3\underset{\underset{\text{O}}{||}}{C}C{H}_3+CaC{O}_3$
$C{H}_3\underset{\underset{\text{O}}{||}}{C}C{H}_3+3NaOI\underset{\Delta }{\overset{NaOH/I_2}{\to }}C{H}_3\underset{\underset{\text{O}}{||}}{C}{O}^{-}N{a}^{+}+\underset{\text{iodoform}}{CH{I}_3}+2NaOH$
(ii) On dilution of a solution, its specific conductance $decreases$ while its equivalent conductance $increases$.
(iii) Sucrose is a $disaccharide$ and yields upon hydrolysis, a mixture of $glucose$ and fructose.
(iv) More $positive$ the standard reduction potential of a substance, the$greater$ is its ability to displace hydrogen from acids.
(v) An aqueous solution of $C{H}_{3}COONa$ is $basic$ due to $anionichydrolysis$ .
$C{H}_{3}CO{O}^{-}+H_{2}O\to C{H}_{3}COOH+O{H}^{-}$
