How many right angle, bond angles are present in TeF5^- molecular ion? — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: O2 is homonuclear and has non-polar bonds. CHCl3 contains polar bonds and has a net dipole moment due to its asymmetrical tetrahedral geometry. Step 2: CF4 contains polar C-F bonds because fluorine is much more electronegative than carbon. Step 3: However, CF4 has a highly symmetric regular tetrahedral geometry where all four C-F bond dipoles cancel each other out completely, yielding a net dipole moment of zero. This matches option (c).
