WebSep 5, 2024 · Phenol (C6H5 OH) is the simplest phenyl-included compound. The resonance stability of certain phenols is often said to make them stronger acids than aliphatic alcohols (pKa = 10 vs. 16-18). However, the main factor is that it is more electronegative of the sp2 α-carbons of phenol compared to the sp3 α-carbons of aliphatic alcohols. WebNucleophilicity refers to the ability of a nucleophile to displace a leaving group in a substitution reaction. We describe various trends in nucleophilicity in this section. There is a trend within a period, a trend within a group, a trend based on the charge of the nucleophile, and a steric effect of the nucleophile.
