Write three different chemical reactions showing the conversion of ethanoic acid to sodium ethanoate. Write balanced chemical equation in each case. Write the name of the reactants and the products other ethanoic acid and sodium ethanoate in each case.
When ethanol reacts with ethanoic acid in the presence of conc. H2SO4, a substance with fruity smell is produced. Answer the following:-
(i) State the class of compounds to which the fruity smelling compounds belong. Write the chemical equation for the reaction and write the chemical name of the product formed.
(ii) State the role of conc. H2SO4 in the reaction.

Give a reason for Conductivity of dilute hydrochloric acid is greater than that of acetic acid
State any two uses of esters.
The substance which can produce brisk effervescence with baking soda solution is:
(a) ethanol
(b) vegetable oil
(c) vinegar
(d) soap solution(b) hydrocarbon ends directed towards the centre and ionic ends directed outwards
In a soap micelle, the soap molecules are arranged radially with the hydrocarbon ends, i.e. hydrophobic, directed towards the centre; and, ionic ends, i.e. hydrophilic, directed outwards.
Write the names of the first three members of the carboxylic acid series.
What do you observe when acetic acid is added to ethyl alcohol in the presence of sulphuric acid?
A student adds 4 mL of acetic acid to a test tube containing 4 mL of distilled water. He then shakes the test tube and leaves it to settle. After about 10 minutes he observes:
(A) a layer of water over the layer of acetic acid
(B) a layer of acetic acid over the layer of water
(C) a precipitate settling at the bottom of the test tube
(D) a clear colourless solution
Fill in the blank with appropriate word/words.
Vinegar is a solution of about ________per cent ________in water.
Write a fully balanced equation for the folowing case:
Acitic acid is warmed with ethanol in the presence of concentrated sulpheric acid.
State the observation
When the gaseous product obtained by dehydration of ethyl alcohol is passed through bromine water.
Raina while doing certain reactions observed that heating of substance ‘X’ with a vinegar-like smell with a substance ‘Y’ (which is used as an industrial solvent.) in the presence of conc. Sulphuric acid in a water bath gives a sweet-smelling liquid ‘Z’ having molecular formula C4H8O2. When heated with caustic soda (NaOH), ‘Z’ gives back the sodium salt and the compound ‘Y’.
Identify ‘X’, ‘Y’, and ‘Z’. Illustrate the changes with the help of suitable chemical equations.
Name the oxidising agent used in the conversion of ethanol to ethanoic acid.
