Reaction of HBr with propene in the presence of peroxide gives

1. iso-propyl bromide

2. 3-bromo propane

3. allyl bromide

4. n-propyl bromide

The reaction of toluene with ${\mathrm{Cl}}_2$ in the presence of ${\mathrm{FeCl}}_3$ gives 'X' and reaction in presence of light gives 'Y'. Thus, 'X' and  'Y' are

1. X = benzal chloride, Y= o-chlorotoluene

2. X = m-chlorotoluene, Y= p-chlorotoluene

3. X = o and p-chlorotoluene, Y = trichloromethyl benzene

4. X = benzal chloride, Y = m-chlorotoluene

The compound formed when acetylene is passed through dilute sulphuric acid in the presence of mercury(II) sulphate is:

1. Ether

2. Ketone

3. Acetic acid

4. Acetaldehyde
