Document Summary
Organic chemistry 2213: typically when hydrogen atoms are shown it is to shown the orientation of the molecule, electron density is the # of groups surrounding the element. Topic 1, chapter 2 acid and base reactions: Acid base reactions are in equilibrium but typically favour one side (one arrow to denote bias) Water can accept or donate a proton (h+) Strong acids have the ability to dissociate almost completely into h+ and the conjugate base: conjugate bases produced by strong acids are very weak (not proton hungry) Weak acids produce strong conjugate bases (very proton hungry) Curved arrows: to show the movement of a pair of electrons, with a full arrowhead to indicate. Acetic acid (vinegar) + water to conjugat4e base and conjugate acid. The tail of an arrow is where the electrons are and the head is where they go pka values can help predict the strength of an acid in water: Ha + h2o a- + h3o+
