What does a very small equilibrium constant (k≪ 1) tell you about the reaction? view available hint(s)
a. the reaction mixture contains large amounts of reactants (relative to the amount of products) at equilibrium.
b. the reaction mixture contains similar amounts of reactants and products at equilibrium.
c. the reaction mixture contains large amounts of products (relative to the amount of reactants) at equilibrium.
d. the reaction mixture contains only reactants.

answer: i dont know the answer but this might

explanation:

l

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.
