Pick out the wrong statement.

• Alkylation produces a larger iso-paraf-fin (having higher octane number) from the reaction of an olefin with smaller iso-paraffin.
• Catalytic alkylation processes use HF, AlCl3 & H2SO4 as Catalysts.
• All the alkylation processes use very high temperature (> 1000°C).
• Gasoline having an octane number of 90 can be produced by alkylation process.
