4. Cole and Blayne were attempting to push Hailey on a wheeled chair
with enough force so
Hailey would run into Mr. Young. They figured out they needed a 50 N force to run the chair into Mr.
Young. Cole and Blayne were both applying force toward Mr Young. Cole was applying a 20 N force
to the left, and Blayne was applying (with all of his strength) a force of 15 N to the left.
a. Draw a force diagram
b. What was the net force if we ignore friction? 15n
c. Did the Hailey chair rocket hit Mr.
Young?
d. How can they get it to hit
him?
no

a electronegativity decreases beacuse the size of nucleus is bigger.

yes

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.
