How can saline hydrides remove traces of water from organic compounds
Asked by sudipt.kumar | 04 Oct, 2010, 10:09: PM
Expert Answer
Saline Hydride capable of deprotonating a range of even weak Brønsted acids to give the corresponding derivatives. Take an example of sodium hydride which is a saline hydride(NaH) with a organic compound like alcohol.
2 R-OH + 2 NaH → 2 R-O-Na+ + 2H2↑
Alcohols can behave as weak acids, undergoing deprotonation. The deprotonation reaction to produce an alkoxide salt is either performed with a strong base such as sodium hydride or n-butyllithium, or with sodium or potassium metal.
