Reaction between thiol and alcohol
WebOrganic Chemistry Reactions of Alkynes. Alkynes have a very similar reactivity to alkenes. They undergo the electrophilic additions like halogenation and hydrohalogenation. They can also be reduced with the aid of a heterogeneous catalyst or oxidized via several techniques. Alkynes do, however, have a number of unique reactions that you’re ... In contrast, thiols are more acidic than alcohols because the S–H bond is weaker—the size of S and H orbitals results in smaller overlap and therefore weaker bonds (just like HBr is more acidic than HCl) and the resulting anion is more stable because the larger size of S results in the negative charge being … See more Recall that there are several factors that can influence Brønsted acidity. These include: the strength of the bond between the R (C) and the O, S, or N (denoted by “Y” below) and H; the polarity of the bond; and the stability of the … See more Earlier (Chapters 1 and 4), we discussed (at great length) that all three functional groups (–OH, –NH, and –SH) are nucleophilic: that is, they will react at the carbon center that is … See more Before we discuss oxidation of alcohols, it should be clear what we mean by the “oxidation” and “reduction” of carbon compounds. Recall … See more Recall that a good leaving group should be able to accept (in a stable form) the pair of electrons from the bond that breaks. Typically, good leaving groups are weak bases. For this reason, hydroxide (–OH) and amide (–NH2) are … See more
