Here are the essential concepts you must grasp in order to answer the question correctly.
Lewis Bases
A Lewis base is defined as a substance that can donate an electron pair to form a covalent bond. This concept is fundamental in understanding acid-base reactions in organic chemistry, where the strength of a Lewis base is determined by its ability to share electrons. Factors such as electronegativity, steric hindrance, and the presence of electron-donating groups influence a compound's basicity.

Basicity Trends
Basicity trends in organic chemistry refer to the relative strength of Lewis bases, which can be influenced by the structure and electronic properties of the molecules involved. For example, basicity generally increases with the availability of lone pairs and decreases with the presence of electronegative atoms that can withdraw electron density. Understanding these trends helps in predicting the reactivity of different Lewis bases in chemical reactions.

Solvation Effects
Solvation effects describe how solvent molecules interact with solute ions or molecules, impacting their reactivity and stability. In the context of Lewis bases, solvation can stabilize or destabilize the base, affecting its ability to donate electron pairs. For instance, a highly solvated Lewis base may be less reactive than a less solvated one, as the solvent molecules can hinder the base's interaction with electrophiles.
