One mole of dissolved particles depresses the freezing point of 1,000 g of water by1.86°C. At standard pressure, what will the freezing point of a solution be if it contains 1,000 g of water and:

1 mol of antifreeze (C, H.0,)?
1 mol of salt (NaCl)?

it is the most commonly accepted one

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.
