Satinder Malhotra Solutions for Chapter: Carbon and its Compounds, Exercise 1: MOCK TEST

Name the reaction which is usually used for the conversion of vegetable oils to fats. Explain the reaction involved and write a chemical equation to illustrate your answer.

What would be observed when a $5\%$ solution alkaline potassium permanganate solution is added to ethanol and the solution is warmed.

A mixture of ethyne (acetylene) and oxygen is burnt for welding. Can you tell why a mixture of ethyne and air is not used?

Why is the conversion of ethanol into ethanoic acid is an oxidation reaction?

Esters are sweet smelling substances and used in making perfumes. Suggest some activity and the reaction involved for the preparation of an ester with well labelled diagram.

A salt ''$\mathrm{X}$" is formed and a gas is evolved when ethanoic acid reacts with sodium hydrogen carbonate. Name the salt '$\mathrm{X}$’ and the gas evolved. Describe an activity and draw the diagram of the apparatus to prove that the evolved gas is the one which you have named. Also, write chemical equation of the reaction involved.

An organic compound $\left(\mathrm{A}\right)$ with the molecular formula, ${\mathrm{C}}_4{\mathrm{H}}_8{\mathrm{O}}_2$ on alkaline hydrolysis, gives two compounds $\left(\mathrm{B}\right)$ and $\left(\mathrm{C}\right)$. $\left(\mathrm{C}\right)$ on acidification with dilute hydrochloric acid gives $\left(\mathrm{D}\right)$. Oxidation of $\left(\mathrm{B}\right)$ with ${\mathrm{K}}_2{\mathrm{CrO}}_4/ {\mathrm{H}}_2{\mathrm{SO}}_4$ also gives $\left(\mathrm{D}\right)$. Identify $\left(\mathrm{A}\right)$, $\left(\mathrm{B}\right)$, $\left(\mathrm{C}\right)$ and $\left(\mathrm{D}\right)$ and explain all the reactions involved there in.

Name a chemical added to water to remove permanent hardness of water.
