Bonds, Bond Polarity, Molecular Polarity, and IMFs

Match may work weird so please do it at your own risk

Ionic

start with a metal

Covalent

start with a non metal (unless it is O2, N2, or Cl2, and if bond occurs between carbon and hydrogen)

Non - Polar

electrons (e-) equally shared

Polar

electrons (e-) not equally shared

Polar

Dipole Moment - atom with higher electronegativity has greater share of e-

Molecular Polarity

determined by Bond Polarity 1st, and if polar, refer to geometric shape

Polar

geometric shape is distorted/asymetrical

Non-Polar

shape is symetrical

London Dispersion

weakest force

London Dispersion

only in NON Polar molecules

Dipole-Dipole

in polar molecules that DON’T have hydrogen bonding between H-O, H-F, or H-N

Dipole-Dipole

gets stronger as mass increases (not the strongest)

Dipole-Dipole

seen with dipole moments, and with terminal atoms with heavier weight than central atom (ex. SBr2)

Hydrogen Bonding

strongest IMF

Hydrogen Bonding

seen in POLAR compounds between H and O,F, or N
