"(Situation) In my current role, I am responsible for creating the weekly schedule for 56 staff members. (Task) When I first took on the responsibility of scheduling, I did not have any data regarding our busiest times of the week and day. (Action) I worked hard to 'guesstimate' our customer traffic while remaining under the staffing budget and, at the same time, not understaffing. I used my logic and critical thinking skills to fill in the blanks for the data that I did not have. (Result) This scheduling approach worked out quite well for me. Now I fully understand our customer traffic flow, which has made staff scheduling a breeze."

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

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.
