State your observations when:

1.      The gas which is obtained by the dehydration of Ethyl alcohol is passed into Bromine water.

2.      Acetic acid is heated with Ethyl alcohol in presence of conc. Sulphuric acid.

3.      Acetic acid is added neutral Ferric chloride solution.

4.      The gas obtained in the dehydrogenation of Ethyl bromide is passed through acidified Potassium permanganate solution.

5.      Acetylene is treated with Ammoniacal Silver nitrate solution.

6.      Ethyl alcohol is burnt in presence of sufficient Oxygen.

Give reasons

1.      Alkenes are more reactive than alkanes.

2.      Alkenes undergo addition reactions but alkanes do not.

3.      Hydrocarbons are excellent fuels.

4.      Pure Acetic acid is called glacial acetic acid.

5.      Alkenes decolourize Bromine water but alkanes do not.
