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.
The primary intermolecular force present in ethanol is hydrogen bonding. Dipole-dipole forces occur when polar molecules are attracted to one another. Basically, if one atom on the molecule is more electronegative than the others, it will pull electrons toward itself, giving it a partial negative charge.
