Which prediction about a methane molecule would most likely be made by using both the quantum model of the atom and john dalton's model? a. when the molecule reacts new atoms are created b. the molecule contains different kinds atoms c. the nucleus is located in the center of the molecule d. electrons are located at specific locations in the molecule.

B.the molecule contains different kinds atoms

Explanation:

Let's go through each choice.

A.when the molecule reacts new atoms are created

Both quantum model of the atom and John Dalton's model recognize that the atoms are not either created or destroyed in a chemical reation, so when a molecule reacts it forms one or more new molecules with the same atoms of the original molecule.

B. the molecule contains different kinds atoms

Indeed, John Dalton's model already considered that the compounds (molecules) are formed by the combination of different kinds of atoms. This is valid nowadays under the quantum model.

C. the nucleus is located in the center of the molecule

Firstly note that John Dalton's model did not consider the existence of a nucleus as the atom was thought to be indivisible. Secondly, quantum model considers that the nucleus is at the center of the atom, not of the molecule.

D. electrons are located at specific locations in the molecule.

John Dalton's model did not consider that the existence of electrons, since, as already said, the atoms was considered indivisible. Regarding quantum model, electrons are not located at specific locations but the model states the probability of finding the electrons in certain regions. The regions with high probability of containing the electros are called orbitals.

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.
