318208 Identify the conditions under which hydrogenation of benzene produces cyclohexane.

1 High temperature, high pressure, Nickel catalyst.
2 Low temperature, low pressure, ZieglerNatta catalyst.

CHXI13:HYDROCARBONS

318209 The correct statement is

1 cyclohexadiene and cyclohexene cannot be isolated with ease during contorlled hydrogenation of benzene
2 one mole each of benzene and hydrogen when reacted gives \(1 / 3\) mole of cyclohexane and \(2 / 3\) mole unreacted hydrogen
3 hydrogenation of benzene to cyclohexane is an endothermic process
4 it is easier to hydrogenate benzene when compared to cyclohexene
