Which of the following structure is similar to graphite?

Question

$\textbf{Reduction potential of ions are given below:}$
\[ \begin{array}{ccc} \text{ClO}_4^- & \text{IO}_4^- & \text{BrO}_4^- \\ E^\circ = 1.19 \, \text{V} & E^\circ = 1.65 \, \text{V} & E^\circ = 1.74 \, \text{V} \\ \end{array} \]
The correct order of their oxidising power is:

Answer 1

To determine which structure is similar to graphite, we need to understand the structure of graphite and the given options.

Graphite is a crystalline form of carbon where the carbon atoms are arranged in layers of hexagonal arrays. These layers are bonded together by van der Waals forces, which makes them slide over each other easily, giving graphite its lubricating properties.

Let's evaluate each option:

$B_2H_6$ (Diborane): This is a boron hydride compound with a unique 3-center 2-electron bond, not similar to the layered structure of graphite.
$BN$ (Boron Nitride): Boron nitride can have a hexagonal structure similar to graphite, where atoms are arranged in layers like graphite. It is often referred to as "white graphite" due to its similar structural properties.
$B$ (Boron): Boron itself does not form structures like graphite. Its common allotropes include amorphous and crystalline forms, which do not exhibit layered structures.
$B_4C$ (Tetraboron carbide): This compound forms complex crystal structures and is used as an abrasive or in armor. Its structure is not similar to graphite.

The correct answer is $BN$, as it can adopt a hexagonal structure similar to that of graphite, thus mimicking the layer arrangement.
