Asolution contains 4.87 mm of an analyte, x, and 1.91 mm of a standard, s. upon chromatographic separation of the solution, peak areas for x and s are 3687 and 10527, respectively. determine the response factor for x relative to s. f= to determine the concentration of x in an unknown solution, 1.00 ml of 8.85 mm s was added to 6.00 ml of the unknown x solution and the mixture was diluted to 10.0 ml. after chromatographic separation, this solution gave peak areas of 6147 and 4497 for x and s, respectively. determine the concentration of s in the 10.0 ml solution. [s] = mm determine the concentration of x in the 10.0 ml solution. [x] = mm determine the concentration of x in the unknown solution. [x] = mm

hydrocarbons are organic compounds that contain only hydrogens and carbons. they can be saturated (those which contain only carbon-carbon single bonds) or unsaturated (those which contain carbon-carbon double or triple bonds) in nature. hydrocarbons can undergo several reactions like substitution, elimination etc.  

on substituting one or more hydrogen atoms in hydrocarbon it results in the formation of haloalkane. as the halogen atoms are large compared to the carbon and hydrogen atoms, due to which the molecular weight increases and the bond become polar because of presence electronegative halogen atom and results in the increase in boiling point of the haloalkane.

thus, the correct option is (b) that is the boiling point of the new compound increases on substituting a hydrogen atom with a halogen in a hydrocarbon.
