Q
Covalent Bond Facts:
A
• Sharing of electrons, • Between molecules of elements: (Cl2, H2, O2) • Single, Double or Triple. • CAN be POLAR (atoms shared are different. HCL) • CAN be NON-Polar (Atoms shared are same. H2)
1
Q
Intramolecular Forces
A
Force WITHIN Molecules.
• Covalent bond.
2
Q
Intermolecular Forces:
DISPERSION Forces:
A
Are very weak forces, temporarily attracted due to electron clouds.
3
Q
Intermolecular Forces:
Dipole-Dipole:
A
Stronger than dispersion,
Permanent attractive forces between + and – ends of a POLAR molecule,
Due to even distribution of charges.

VERY strong between F, O, and N.
