Compare van der waals forces ionic bonds and covalent bonds

        1) Covalent bond: The bond that is formed by mutual sharing of electrons.

       2) Ionic bond: The bond that is formed by complete transfer of electron from one atom to an other atom.

         3) Van der waal: These are weak interactions between one molecules with other polar or non polar molecules to hold to each other.

Explanation:

a) Similarities between van der waal and ionic bonds:

As both are considered as a inter-molecular forces, however ionic bonds are stronger than van der walls forces.

b) Difference between van der waal and ionic bonds:

As ionic bonds are formed by complete transfer of electrons from one atom to an other atom while in van der waal, a slight attraction is develop when oppositely charged regions molecules come close to each others.

c) Difference between ionic and covalent bonds:

As both are strong bond, but if we compare both, the ionic bond are stronger than covalent bond.

Covalent bonds are bonds formed between two non-metals, while Ionic bonds are formed between a metal and a non-metal.

answer: option (b) is the correct answer.

explanation:

a covalent bond is formed by sharing of electrons. whereas polarity arises due to difference in electronegativity of two atoms.

therefore, more is the electronegativity of an atom which combines with the titanium, more readily it will induce a partial positive and negative charge.

thus, out of the given options fluorine is most electronegative and has an incomplete octet. therefore, it will readily combine with titanium to share the electrons and complete its octet.
