By which of the following process hydrocarbons are found from petroleum?
Combustion
Fractional distillation
Addition
All of the above
The false statement regarding alkane is
this does not perform polymerization reaction
this does not gives elimination reaction
it does not disappear the colour of dilute KMnO4 solution
it does not decolourise bromine water
B.
this does not gives elimination reaction
Alkanes show elimination reactions. Higher alkanes eliminate hydrogen and lower alkanes on heating in the absence of air at 500-700°C.
Which of the following aromatic compound gives sulphonation reaction very easily?
Chlorobenzene
Nitrobenzene
Toluene
Benzene
C2H6 + CH3Cl C6H5CH3 + HCl
The name of the above reaction is
Gattermann
Reimer-Tiemann
Friedel-Craft
Cannizzaro
The tetraethyl lead mixed in petrol works as
cooling agent
anti-knocking agent
bleaching agent
None of the above
