Analysis of XeOF4 molecule:
Bond pairs around Xe (x):
In XeOF4, xenon (Xe) has 4 oxygen (O) atoms bonded to it, resulting in 4 bond pairs. Therefore, x = 4.
Lone pairs around Xe (y):
Since Xe is in group 8 (18) of the periodic table, it has 8 valence electrons. In XeOF4, each fluorine (F) atom contributes one electron to form a bond with Xe. So, the total electrons used in bonding are 4 (from O atoms) + 4 (from F atoms) = 8. This leaves Xe with 8 - 8 = 0 lone pairs. Therefore, y = 0.
90° angles with respect to angle OXeF (z):
In XeOF4, each of the 4 oxygen atoms bonded to Xe is positioned at 90° angles with respect to each other. Therefore, z = 4.
Total sum of x, y, and z:
Adding the values of x, y, and z:
x + y + z = 4 + 0 + 4 = 8
Therefore, the total sum of bond pairs, lone pairs, and 90° angles in XeOF4 is 8.
Final Answer:
The correct choice is (d) 8.
