Problem: In the following pair of binary compounds determine which one is a molecular substance and which one is an ionic substance. TiCl4 and CaF2.

FREE Expert Solution

We are asked to determine which one is a molecular substance and which one is an ionic substance between TiCl4 and CaF2.


Let’s first define an ionic and molecular bond:

Ionic Bond

involves the transferring of an electron from one element to another element
positively charged ion + negatively charged ion

metal → usually is the positively charged ion (+)
nonmetal → usually is the negatively charged ion (-)
metal(or polyatomic ion) + nonmetal (or polyatomic ion)


Covalent (or Molecular) Bond

involves the sharing of electron(s) between elements

nonmetal + nonmetal
