Methylamine is a naturally colorless gas, and a derivative of ammonia. Sometimes it is sold and methanol and ethanol. It's natural use is in plants, which it serves as a buffering agent in the lumen (a membrane of plants) of the chloroplast. It then takes off the protons that are used in ATP synthase. Methylamine is also very good at dissolving organic substances, more so than liquid ammonia.
There are 3 types of forces of attraction and all of these happen to apply to methylamine.
The first is London Dispersion. Dispersion forces are caused by the motion of electrons, and it causes temporary poles. Dispersion forces exist between every molecule at one time or another, between two molecules that ocme close together. It is the weakest of all three forces, and it is also the only force that attractions 2 nonpolar molecules
The second force of attration is Dipole Dipole. This type of force occurs within molecules with two oppositely charged ends and it's a permanent force of attraction. It occurs due to the electrostatic attraction between positive and negative charges. In methylamine, the dipole dipole occurs because of the seperation of charges between carbon and nitrogen
The last force of attraction is Hydrogen Bonding. Hydrogen bonding is a special case of dipole dipole, and the strongest of the three. What sets it apart from dipole dipole is that there most be a bond between hydrogen and either oxygen, flourine, or nitrogen. In methylamine, hydrogen is bonded to nitrogen.
