Test Quiz;
electron dot formulas for Ionic, Covalent, polyatomic ions, tell if molecule is P or NP, shape and angle and circle any ;lone pairs (they are only on the central atom)
For the following compounds, Choose the strongest attractive forces present in each of the following.
(A) hydrogen bonding
(B) dipole – dipole forces
(C) dipole-induced dipole forces
(D) ion – dipole forces
(E) London dispersion forces
for example: water, ammonia CH4, CO2 - which IMF do they have and therefore which has the highest boiling point within the pair?
