Which list correctly orders intermolecular forces from weakest to strongest?

a. london dispersion forces, dipole interaction forces, hydrogen bonding

b. hydrogen bonding, dipole interaction forces, london dispersion forces

c. dipole interaction forces, london dispersion forces, hydrogen bonding

d london dispersion forces, hydrogen bonding, dipole interaction forces

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.  

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.
