Pi bonds bases
WebbA Brønsted-Lowry base is a proton (hydrogen ion) acceptor. When a Brønsted acid HA dissociates in water, it increases the concentration of hydrogen ions in the solution, [H+] … WebbSince we know that these acids do not react with alkanes, it must be the pi-electrons of the alkene double bond that serve as the base. As shown in the diagram on the right, the pi-orbital extends into the space immediately above and below the plane of the double bond, and the electrons occupying this orbital may be attracted to the proton of a Brønsted acid.

For example, a double bond has one pi bond and a triple bond has two pi bonds. Pi bonds cannot rotate because that would require the break of the parallel orientation of the p-orbitals.

So the pattern is, a lone pair of electrons, so next to a pi bond, which is the example we see here for the acetate anion, and so these are the two resonance structures. The problem with the word ... Webbboth have a lone pair or a π bond. Bases attack: protons Nucleophiles attack: carbons How is nucleophilicity (nucleophile strength) related to basicity? Although it is generally true that a strong base is a strong nucleophile, nucleophile size and steric factors can sometimes change this relationship. Nucleophilicity
