Number of vertices in an icosahedral closo-borane is __________.Correct answer is between '12,12'. Can you explain this answer?

Question

Answer

Explanation:

An icosahedral closo-borane is a polyhedral molecule consisting of boron atoms and hydrogen atoms. It is a type of closo-borane, which means that all the vertices of the polyhedron are occupied by boron atoms.

Formula:

The formula for an icosahedral closo-borane is B12H12. This means that there are 12 boron atoms and 12 hydrogen atoms in the molecule.

Vertices:

The vertices of a polyhedron are the points where the edges of the polyhedron meet. In the case of an icosahedral closo-borane, each vertex is occupied by a boron atom. Therefore, the number of vertices in an icosahedral closo-borane is equal to the number of boron atoms in the molecule.

Conclusion:

The correct answer is 12, which is the number of boron atoms in an icosahedral closo-borane.
