Question

(a) How will you bring about following reactions? Write the concerned chemical equations (i) Ethanol to Ethene (ii) Ethanol to Ethanoic acid (b) Give one example with chemical equation for the following reactions : (i) Substitution reaction (ii) Saponification reaction(iii) Combustion reaction

Answer 1

Answer:

Explanation:

Don't know

Answer 2

(a) Conversion reactions -

(i) Ethanol to Ethene -

Ethene is obtained by adding conc.H2SO4 to ethanol.

CH3-CH2-OH --> CH3=CH2 + H2O.

(ii) Ethanol to Ethanoic acid -

Ethanol on reaction with acidified potassium dichromate gives ethanoic acid.

CH3CH2OH + 2[O] → CH3COOH + H2O

(b) Example of reactions -

(i) Substitution reaction -

Methane on reaction with chlorine gives methyl chloride.

CH4 + Cl2 --> CH3Cl + HCl

(ii) Saponification reaction -

Ethanoic acid on reaction with aq.NaOH gives sodium ethanoate.

C2H5COOH + NaOH --> C2H5COONa + H2O

(iii) Combustion reaction -

When methane burns in air, it forms CO2 & water.

CH4 + 2O2 --> CO2 + 2H2O
