Nonpolar vs Polar covalent

Postby Melody Haratian 2J » Wed Nov 18, 2020 10:24 pm

Hi guys! So covalent bonds are polar when the electrons are shared unequally and they’re nonpolar when the electrons are shared equally. Usually, how close do the atoms have to be in electronegativity for a bond to be considered nonpolar.
Also, are C-H bonds considered nonpolar?
Thanks!

I think a difference of 0.4 or less leads to nonpolar covalent bonding. Following that rule, a C-H bond would be nonpolar.
