WebIn organic chemistry, a nitrile is any organic compound that has a −C≡N functional group. The prefix cyano-is used interchangeably with the term nitrile in industrial literature. Nitriles are found in many useful compounds, including methyl cyanoacrylate, used in super glue, and nitrile rubber, a nitrile-containing polymer used in latex-free laboratory and medical … WebTake for example ammonia (NH3). Ammonia has a pKa of 38. Thus, any molecule with a pKa less than 38 will protonate ammonia, and if the pKa of the molecule is greater than ammonia, NH3 will deprotonate it. Ammonia will be protonated by acetic acid (pKa 4.76), but deprotonated by an alkane with a negative charge/lone pair (pKa 50).
