WebJan 23, 2024 · Here we will go through the following reactions listed below to learn the mechanisms behind these electrophilic additions of alkynes: (1) HX Addition to Alkenes, (2) Halogenation of Alkynes and (3) Hydration of Alkynes. Figure 1. The addition of an electrophile to either an alkene or an alkyne will undergo the same steps listed below. WebMay 22, 2024 · Addition of HCN to the carboxyl compounds is a nucleophilic addition reaction. The reactivity towards HCN addition decreases as the + I effect of the alkyl groups increases and/or the steric hindrance to the nucleophilic attack by CN– at the carboxyl carbon increases. Thus the reactivity decreases in the order
