Question

Given,$BC{l_3} + Hg\xrightarrow{\vartriangle }white{\text{ppt + X}}$ in gas phase what is the maximum number of coplanar atoms in $X$ :
A. $4$
B. $5$
C. $6$
D. $7$

Answer 1

The vaporous stage isn't destructive, yet when gases, for example, carbon dioxide, and oxygen break down in the fluid water stage, they impact the destructiveness of the watery stage. The grouping of gas in the arrangement is straightforwardly corresponding to its halfway pressing factor in the gas stage (Henry's law).

Complete answer:
We have to know that, co-planar is essentially utilized for a ring where the component, which is reinforced with ring (outside the ring) is in a similar plane or not
In math, a bunch of focuses in space are coplanar if there exists a mathematical plane that contains them all. For instance, three focuses are consistently coplanar, and if the focuses are particular and non-collinear, the plane they decide is one of a kind. Notwithstanding, a bunch of at least four unmistakable focuses will, by and large, not lie in a solitary plane.
Two lines in three-dimensional space are coplanar if there is a plane that incorporates them both. This happens if the lines are equal, or on the off chance that they converge one another. Two lines that are not coplanar are called slant lines.
Distance math gives an answer strategy to the issue of deciding if a bunch of focuses is coplanar, knowing just the distances between them.
The balanced chemical equation is given below,
$2BC{l_3} + 2Hg\xrightarrow{\vartriangle }{\text{H}}{{\text{g}}_2}{\text{C}}{{\text{l}}_2} \downarrow {\text{ + }}{{\text{B}}_2}C{l_4}$
Therefore,
The maximum number of coplanar atoms are present in $X$ is four.

So, the correct answer is “Option A”.

Note:
We have to know that reduction in the vaporous stage is one of the strategies utilized for the creation of metallic nanoparticles and it is primarily utilized specifically for the amalgamation of iron gathering metals nanoparticles at research center scale. The technique comprises stages, like molecule arrangement, molecule aggregation, and gas washing.
