Embibe Experts Solutions for Chapter: Aldehydes, Ketones and Carboxylic Acids, Exercise 3: Level 3

Which carbonyl group is most reactive for nucleophilic addition reaction ?

End product $\left(\mathrm{B}\right)$ of above reaction

Which of the following compound does not give Tollen's test?

Number of all possible aldol products (including stereoisomers) are

The degree of unsaturation in major product $\left(\mathrm{B}\right)$ will be:

(i) Number of compounds which do not react with Fehling solution are $\mathrm{x}$ ?

${\mathrm{CH}}_3\mathrm{CHO},\mathrm{Ph}-\mathrm{CHO}$, Glucose 

(ii) Tollen’s reagent can be used to distinguish between $\mathrm{y}$ number of pairs:

 and ${\mathrm{CH}}_3\mathrm{CH}{\left({\mathrm{OCH}}_3\right)}_2$,  and ${\mathrm{CH}}_3{\mathrm{COCH}}_3, {\mathrm{CH}}_3\mathrm{CHO}$ and $\mathrm{HCOOH}, {\mathrm{CH}}_3\mathrm{CHO}$ and ${\mathrm{CH}}_3{\mathrm{COCH}}_3$

[Give your answer as $\mathrm{x}+\mathrm{y}$]

${\mathrm{P}}_2+{\mathrm{FeCl}}_3⟶\mathrm{Red} \mathrm{colour}$

${\mathrm{P}}_1+\mathrm{NaOI}⟶\underset{\mathrm{Yellow}}{{\mathrm{P}}_3\downarrow }+{\mathrm{P}}_4$

If $\mathrm{x}=$ Molecular mass of gas obtained when ${\mathrm{P}}_3$ is treated with $\mathrm{Ag}$ powder. $\mathrm{y}=$ Molecular mass of aromatic hydrocarbon obtained when ${\mathrm{P}}_4$ is treated with soda lime $/\mathrm{\Delta }$. Then value of $\left(\frac{\mathrm{y}}{\mathrm{x}}\right)$ is....
