What is the strongest interparticle force in a sample of solid mgcl2?

The strongest inter particle force in is electrostatic force of attraction.

Explanation:

Magnesium chloride is an ionic compound which is formed by the combination of magnesium ions and chloride ions.

Ionic compounds are defined as the compounds which are formed by the complete transfer of electrons from one atom to another atom.

In these compounds, oppositely charged ions are attracted towards each other to form a compound.

The attraction between oppositely charged species is very strong and is known as electrostatic force of attraction.

Hence, the strongest inter particle force in is electrostatic force of attraction.

1 is the answer to this problem

substituting a hydrogen atom with a halogen in a hydrocarbon:

- the single bond remains single. a is wrong.

- the bond with hydrogen is as strong as with a halogen. c is wrong

- a hydrocarbon is saturated if there is no double bond. we do not know that so d is wrong.

- carbon will always have four valence electrons. e is wrong.

by elimination, the correct answer is b. the boiling point of the new compound increases.
