Identify each of the following changes of state as evaporation, boiling, or condensation: a. The water vapor in the clouds changes to rain.
b. Wet clothes dry on a clothesline.
c. Lava flows into the ocean and steam forms.
d. After a hot shower, your bathroom mirror is covered with water

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.
