Decide if the compound/ion listed can satisfy the octet rule (duet rule for h), if so choose satisfies octet ruleif the compound/ion cannot satisfy the octet rule for one of the atoms in the formula, choose one of the following three reasons why; too many valence electrons (more than eight), too few valence electrons (fewer than eight), or odd # of valence electrons. krcl2pcl5co3^2-no2no3-ocl2

the answer is 303.15 or 303

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.
