The molecular geometry of is pentagonal bipyramidal. Excluding the axial-axial angle, what are the c — Chemical Bonding Chemistry Question

💡 Solution & Explanation

In a pentagonal bipyramidal structure ($sp^3d^3$), the 5 equatorial bonds are separated by $360/5 = 72^\circ$. Each of the 2 axial bonds sits at $90^\circ$ relative to all 5 equatorial bonds, yielding $2 \times 5 = 10$ angles of $90^\circ$.
