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.
In fact, because hydrogen is so much less electronegative than oxygen, there is a strong intermolecular force known as hydrogen bonding present in water. Hydrogen bonding is an exceptional case of dipole-dipole interactions. In oxygen gas, intramolecular forces are nonpolar covalent. The forces are covalent for the same reasons as above: oxygen is a nonmetal, and in oxygen gas, oxygen is bonded with only oxygen.
