Which of the following descriptions explain the process of water freezing?
a. what're molecules speed up until the escape into a different phase.
b. water molecules slow done until they begin to form stronger bonds together.
c. as water molecules cool, their shape changes from rounded to irregular, making them more likely to link to one another
d. water molecules are squeezed together by high pressure until they begin to stick to one another.

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.
