For 10 points, name these substances that have a pH of greater than 7, contrasted with acids.
One theory of these substances states that one type of them possesses a low-energy HOMO, low polarizability, and high electronegativity; that theory was put forth by Pearson. In general, increased strength of these substances is correlated with increased nucleophilicity, unless steric groups are present, such as in triethylamine or LDA. Alkanes containing a leaving group can be converted to alkenes by adding one of these substances, such as sodium hydride. Lewis defined these substances as electron donors, while BrÃ¶nsted and Lowry defined them as proton acceptors. These substances turn methyl red yellow and phenolphthalein pink.
