the process which involves the replacement of hydrogen atom of alkane with the sulphonic acid group (HSO3-) is known as sulphonation of alkane
it is carried out by heating higher alkane with fuming sulphuric acid
C6H13H + HOSO3H = C6H13SO3H + H2O
the sulphonation of alkane is proceeds by free radical mechanism
OH-SO3H = OH + SO3H
R-H + O-H = H2O
R + SO3H = R-SO3H
