WebOct 27, 2024 · pKa is an acid dissociation constant used to describe the acidity of a particular molecule. Its value is directly related to the structure of the given compound. The constant changes depending on the solvent the … One of the most powerful insights from learning the periodic table is the fact elements in the same period (column) have similar chemical properties. For instance 1. Alkali metals (Li, Na, K…) all shed an electron relatively easily to form monovalent cations 2. Halogens (F, Cl, Br) all gain an electron relatively easily … See more Open a textbook that discusses thiols and one of the first things they’ll mention is their vile stench. We wouldn’t want to break with this honourable tradition here at MOC. Hydrogen … See more We’ve seen that alcohols are relatively acidic (pKa‘s of about 16-17). Thiols are more acidic than alcohols by an average of about 5 pKa units or so ( pKa of about 11 for the thiol pictured below).
