Molecular structure: true or false questions?

true or false, and explain why





1. all square planar molecules will a net dipole moment.





2. thiocyanide ion has 3 equally stable resonance structures





3. if a compound has polar bonds then it will be a polar molecule.





the text book is not helping...Molecular structure: true or false questions?
1. false: if they have the same element s opposite each other, they polar bondswill cnacel out


2. Not sure


3. False: polar molecules can cancel out.





sorry about 2
