Ozone which is present in the stratospheric region of atmosphere is helpful for preventing harmful UV rays from reaching the surface of earth. Due to human activity, several compounds (specifically chlorofluorocarbons) are released in atmosphere. Due to inherent chemical stability of these compounds, the remain stable in lower region of atmosphere and slowly diffuse into stratosphere. On reaching the stratosphere, these compounds reacts with ozone and thereby depletes the effective concentration of ozone present in atmosphere. Hence, <span>the Montreal Protocol was signed in 1987 by major countries of the world. This aim of this protocol was to protect the stratospheric ozone layer by phasing out the production and consumption of ozone-depleting substances.</span>

What leads to the formation of an ionic bond with Hg2+?

statuscvo [17]

The attraction of an $SO_4^{2-}$ ion leads to the formation of an ionic bond with $Hg^{2+}$

<h3>What is an ionic bond?</h3>

Ionic bond, also called an electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound.

Since the question asking among all these options:

(a) The attraction of a noble gas

(b) The attraction of a $NH^{4+}$ ion

(d) The attraction of a $SO_4^{2-}$ ion

An ionic bond can be formed after two or more atoms lose or gain electrons to form an ion. Ionic bonds occur between metals, losing electrons, and nonmetals, gaining electrons.

Hence, option D is correct.
