Give me example of rancidity

An example of rancidity is when a chips pack is exposed to atmospheric air which results in a change in taste and odor.

Explanation:

Rancidity is a condition in which the substance with oil and fats get oxidized when they are exposed to air. A substance is said to be rancid when there is a change in smell, taste, and colour.Oil becomes rancid due to decomposition of fats it contains or sometimes milk becomes rancid due to not heating it in humid atmosphere, etc.

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.
