Read the following passage
before rutherford conducted the gold foil experiment, the "plum pudding" model proposed by j. j. thomson offered an explanation for the structure of the atom
rutherford, along with two of his associates hans geiger and emest marsdenperformed an experiment in which an extremely thin metal foil was fired with a beam
of alpha particles. the results of the experiment were recorded accurately by another scientist who observed the frequency of alpha particles that passed through the
foil unobstructed
use information from the passage to justify whether the characteristics of reliable scientific explanations are present in the development of the atomic theory.

bcde is the incorrect answer it is a

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.
