. . . . . . . . is not acidic.
A. PCl4
B. SbCl4
C. CCl4
D. PCl2
Answer: Option C
Solution (By Examveda Team)
* Acidity often comes from a molecule's ability to donate a proton (H+) or accept electrons.* In the context of these chlorides, we need to consider how they react with water (hydrolyze). Some will form acidic solutions because of this reaction.
Now let's look at the options:
* PCl4: This compound is unstable and doesn't exist under normal conditions. But theoretically, if it reacted with water, it could potentially form phosphorus-containing acids.
* SbCl4: Antimony tetrachloride can hydrolyze to form acidic solutions containing antimony oxychlorides and hydrochloric acid.
* CCl4: Carbon tetrachloride (CCl4) is not acidic. It doesn't react with water easily. The carbon-chlorine bond is relatively strong, and there isn't a good mechanism for it to hydrolyze and release H+ ions.
* PCl2: This compound is unstable and doesn't exist under normal conditions. Similar to PCl4 it is capable of forming phosphorus-containing acids.
Therefore:
The answer is CCl4 because it doesn't readily hydrolyze to produce acidic species in water.

The compound that is not acidic among the options provided is CCl4 (carbon tetrachloride).
Here's why:
CCl4 (Carbon Tetrachloride): Carbon tetrachloride is a non-acidic compound. It is a clear, colorless, volatile, and stable chlorinated hydrocarbon. It lacks the ability to donate a proton (H+) or accept an electron pair, which are characteristics of acids and bases, respectively.
PCl4 (Phosphorus Tetrachloride): This is not a stable compound and is not a common compound.
SbCl4 (Antimony Tetrachloride): This compound is a Lewis acid, meaning it can accept an electron pair.
PCl2 (Phosphorus Dichloride): This is not a stable compound and is not a common compound.
