Counterion of strong bases

WebIn chemistry, an alkoxide is the conjugate base of an alcohol and therefore consists of an organic group bonded to a negatively charged oxygen atom. They are written as RO−, where R is the organic substituent. Alkoxides are strong bases and, when R is not bulky, good nucleophiles and good ligands. Alkoxides, although generally not stable in ... WebThe counterion condensation (CC) theory was originally developed to treat an infinitely long line-charge system in an infinitely dilute ionic solution (Manning, 1978 ). The theory has led to several widely used conclusions such as the linear dependence of melting temperature Tm of nucleic helix on the logarithm of salt concentration ( Manning ...

WebVideo transcript. One way to make ethers is to use the Williamson ether synthesis, which is where you start with an alcohol, and you add a strong base to deprotonate the alcohol. Once you deprotonate the alcohol, you add an alkyl halide, and primary alkyl halides work the best. We'll talk about why in a minute.
