\angle FAsF bond angle in AsF3Cl2 molecule is : — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Determine the geometry of AsF3Cl2 (steric number = 5, trigonal bipyramidal). According to Bent's rule, the more electronegative fluorine atoms occupy both axial positions and one equatorial position, while the larger chlorine atoms occupy the remaining two equatorial positions. Step 2: The axial-equatorial F-As-F angle is exactly 90°. Step 3: Therefore, the F-As-F bond angle is 90°, which matches option (c).
