There are substitutions for the flight review which will make you a more competent pilot, learn more, and in some cases it will cost you less than a regular fight review. Before we go into that lets review what a flight review is.
1 Hydrogen bonding is the strongest type of intermolecular force arising from permanent dipole permanent dipole attraction and the partially positive proton end of one molecule attracts the partially negative nitrogen (or oxygen/fluorine) lone pair end of a close neighbouring molecule.
Confidence votes 184. propanol is one of those inorganic molecules that can have both a polar and non-polar end. The polar end (OH-) gives it the ability to have dipole-dipole bonding with other polar molecules while the CH3 end gives it the ability to bond with non-polar molecules using London dispersion forces.
