jisko aata he 7 or 8 jldi solve kr do

Answer 1

7) when ethanol is heated in 443k , the following reaction takes place with the formation of ethene (unsaturated hydrocarbon) and water.
CH3CH2OH---H2SO4------> CH2-_-_ CH2+OH
So now if H2 is added with ethene in the presence of nickel catalyst saturated hydrocarbon namely ethane.
The role of H2SO4 in the above reaction was that it acts as a dehydrating agent.
8) When ethanol reacts with ethanoic acid it forms ester. The reaction is as follows,
CH3CH2OH+CH3COOH ------H2SO4--> CH3COOC2H5
It belongs to the class of compound namely organic compound (ester). Chemical name is methyl methanoate.
ii) H2SO4 acts as a catalyst which helps to proceed the reaction at a greater rate without the reaction itself getting effected.

Answer 2

Hey buddy...
