Out of HF and H2O , which is more polar and why?
WebBecause of the tendency of fluorine to form hydrogen bond, metal fluorides are solvated by $\ce{HF}$ giving species of the type $\ce{HF2-}$ like in $\ce{KHF2}$ $(\ce{KF.HF})$. Also, because of hydrogen bonding, $\ce{HF}$ dimerises to $\ce{H2F2}$ and exhibits dibasic nature and forms acid salt like $\ce{KHF2}$ on reacting with $\ce{KOH}$ whereas ...

Webboiling polar aprotic solvents including DMSO or sulfolane (Scheme 4). Scheme 4 The commonest fluoride source is potassium fluoride, though other fluorides are sometimes used, and improved results can often be obtained if the fluoride ion is solubilized by means of a thermally stable phase-transfer catalyst such as tetraphenyl-phosphonium chloride. crochet patterns for bath mats
