Which phrase is an example of what electrostatic forces hold together?

ag atoms and localized electrons in silver

cs+ and cl− in cscl

ar atoms in argon gas

oxygen and hydrogen atoms in h2o

Cs+ and Cl- in CsCl

Explanation:

An electrostatic force is a force established between positive and negative electrical charges. Also known as the force by which positive and negative charges are attached to each other and by which like forces repel each other.

Long story short, one positive, the other negative.

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.
