Question

Which of the following is/ are soluble in ethanol?
A. \[Hg{F_2}\]
B. \[HgC{l_2}\]
C. \[Hg{I_2}\]
D.All of these

Answer 1

Hint: We must remember that the solvent is a substance which is used to dissolve another substance called solute to form a solution. Solvents are used in paint, paint removers, inks and dry cleaning.

Complete step by step answer:
Ethanol is monohydric alcohol which is produced by the fermentation of sugar. It is an inflammable volatile liquid and is soluble in water also in organic solvents. It is colorless, features a faint odor, and a burning taste. Ethanol affects a part of the brain which controls our muscular movement and so it gives temporary relief from tiredness or fatigue but overconsumption can damage the liver and kidneys too.
In case of option A, \[Hg{F_2}\] is soluble in ethanol because \[Hg{F_2}\] is an ionic compound and is soluble in ethanol. It is also hydrolysed by cold water to sort hydrofluoric acid. The other halides of mercury are much more covalent in nature and have low melting and boiling points as compared to the fluoride. They are also soluble in a variety of organic solvents, and in water and they form complexes. So, this feature is correct.
In case of option B, \[HgC{l_2}\] is soluble only in water not in ethanol because these ions are not as close to the same size. Therefore, the option B is incorrect.
In case of option C, \[Hg{I_2}\] is slightly soluble in ethanol and not completely soluble. Therefore, the option C is incorrect.

Therefore, the solution to this present question is option A that is \[Hg{F_2}\].

Note:
We must understand that the organic compounds tend to dissolve well in solvent that have similar properties to themselves. This chemical nature is often referred to as ‘’like dissolves like’’, which means that polar molecules will generally dissolve well in polar solvents and nonpolar molecules will generally dissolve in non-polar solvents.
