Following is a portion of the periodic table that includes the first 18 elements. For each of these elements, the number of electrons present in each energy level is shown. However, four of these values have been entered incorrectly. Use what you know about each neutral Adam and any patterns you notice in the table data to identify the four incorrect values. Select the four incorrect values in the table

a. they are both space stations

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.
