a student claims the change in average global air temperatures is a result of burning fossil fuels. Explain whether the students claim is plausible based on the data

When fossil fuels are burned, they release nitrogen oxides into the air and has a significant impact on global warming. Nitrogen oxide is 300 times more potent than carbon dioxide, and it also depletes the ozone layer.

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.
