Key Concepts

Basicity as Electron-Pair Donation

Basicity is defined as the ability of a molecule to donate a pair of electrons and accept a proton. The strength of a base is determined by the availability of its lone pair for bonding with a proton. This concept is pivotal in comparing how different compounds, such as hydrides and alkyl derivatives, behave as bases.

Substituent Effects and the Inductive Effect

Substituent effects, particularly the inductive effect, play a crucial role in determining the basicity of a molecule. Alkyl groups, like methyl groups, donate electron density through the inductive effect, enhancing the electron richness of the central atom. This increased electron density in phosphines such as P(CH3)3 makes them stronger bases than their hydride counterparts like PH3.
