Questions using dipole
Problem 1
CH₄ has symmetric tetrahedral geometry. What does that imply for its net dipole in the simple model?
Hints
State what the supplied observations or conditions establish, and separate that from any assumption.
Answer and explanation
The symmetric distribution gives no permanent net dipole.
