Give plausible explanation for of the following : During the preparation of esters from a carboxylic acid and an alcohol in the presence of an acid catalyst, the water or the ester should be removed as soon as it is formed.

In the preparation of ester by reaction of carboxylic acid and an alcohol, the ester is distilled as fast as it is formed. Explain why ?

Why is the ester distilled as fast as it is formed during the preparation of esters from the reaction between alcohol and carboxylic acid ?

How will you prepare carboxylic acids from primary alcohols aldehydes ?

How will you prepare: ethene from ethyl alcohol acetic acid from ethyl alcohol? give reaction

How will you prepare the following ? Give chemical equation also. Phosphoric acid from PCl_5 .

A non-metal A which is the largest consituent of air, when heated with H_2 in 1:3 ratio in the presence of catalyst gives a gas B. on heating with O_2 it gives an oxide C. If this oxide is passed into water in the presence of air it gives an acid D which acts as a strong oxidising agent. To which group of periodic table does this non-metal belong?

Hydrolysis of methyl acetate in aqueous solution has been studied by titrating the liberated acetic acid against sodium hydroxide. The concentration of the ester at different times is given below. Show that it follows a pseudo first order reaction, as the concentration of water remains nearly constant (55 mol L^(-1)), during the course of the reaction. What is the value of k in this equation? Rate = k [CH_3C00CH_3][H_20]

These question consist of two statements each, printed as Assertion and Reason. While answering these questions you are required to choose any one of the following responses If both Assertion and Reason are true and Reason is a correct explanation of Assertion If both Assertion and Reason is a not a correct explanation of Assertion If Assertion is true but Reason is false If both Assertion and Reason are false Assertion: BaCO_3 ​ is more soluble in HNO_3 ​ than in plain water. Reason: Carbonate is a weak base and reacts with the H^+ from the strong acid, causing the barium salt to dissociate.
