Which of the following is the correct angle between the atoms in an octahedral molecule?

A. 90o
B. 120o
C. 180o
D. 270o
B.

I thought there were two angles; one is 90 and the other 180.

To determine the correct angle between atoms in an octahedral molecule, we need to understand the geometry of an octahedral molecule.

An octahedral molecule consists of a central atom surrounded by six other atoms or groups of atoms, forming a symmetrical octahedral shape. The central atom is located at the center of an imaginary octahedron, with the six surrounding atoms or groups located at each of the six vertices of the octahedron.

In an octahedral molecule, the angle between any two adjacent atoms is the same. This angle can be calculated by dividing the total degrees in a circle (360 degrees) by the number of atoms or groups surrounding the central atom.

For an octahedral molecule with six surrounding atoms, we divide 360 degrees by 6 to find the angle between the atoms.

360 degrees / 6 = 60 degrees

Therefore, the correct angle between the atoms in an octahedral molecule is 60 degrees.

B) 120 degrees is not the correct answer for the angle between atoms in an octahedral molecule.
