Which of the following aromatic compound gives sulphonation reaction very easily?
1 Chlorobenzene
2 Nitrobenzene
3 Toluene
4 Benzene
Explanation:
: Sulphonation reaction is an electrophilic substitution reaction. Toluene is more readily sulphonated among these because methyl group is electron donating ( $+\mathrm{I}$ effect). Activate the benzene ring for electrophilic aromatic substitution. Methyl group activates the ring and it easier to undergo electrophilic substitution reaction.

The false statement regarding alkane is
1 This does not perform polymerization reaction
2 This does not gives elimination reaction
3 It does not disappear the colour of dilute $\mathrm{KMnO}_4$ solution
4 It does not decolourise bromine water
Explanation:
: Alkane show the elimination reaction Higher alkane eliminate hydrogen and lower alkane on heating in the absence of air at $500-700^{\circ} \mathrm{C}$.

By which of the following process hydrocarbons are found from petroleum?
1 Combustion
2 Fractional distillation
3 Addition
4 All of the above
Explanation:
: Fractional distillation is separate a mixture into a number of different parts called fractions. Crude oil is a mixture of hydrocarbons. The crude oil is evaporated and its vapours condense at different temperature in the fractionating column. Each fraction contains hydrocarbon molecule with a similar number of carbon atoms and a similar range of boiling points.

LPG mainly consist of the following
1 Methane
2 Hydrogen
3 Acetylene
4 Butane
Explanation:
: Liquefied petroleum gas (LPG) is a blend of light hydrocarbon compound. It is mainly consist of butane or propane or a mixture of both. At room temperature, both gases are colourless and odourless. LPG transforms into a liquid state. LPG in domestic cylinder used for cooking generally comparises more butane than propane, because the fuel value of per kilogram of butane is higher than propane.
