Carbon dioxide is commonly found as a solid (dry ice) or a gas (carbon dioxide gas). jeff's teacher asked him to draw models to show the motion of carbon dioxide molecules that make dry ice different from carbon dioxide gas. describe what was correct and what might be improved about jeff's models in showing the motion of the carbon dioxide molecules that make dry ice different from carbon dioxide gas

Explanation:

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.

the objects have the same charge.
