Description

https://joechem.io/videos/46 for video on jOeCHEM and attached worksheet + solution (below video on jOeCHEM aka the link). In this video, we talk about nucleophiles/electrophiles, different types of solvents, and indulge in a splash of acid-base review. This video is important to lay some groundwork/foundational knowledge that will be needed for learning SN2/SN1/E2/E1.

    Hi Joe! I was doing the worksheet and I don't understand why NH2- is the strongest base instead of OH- Could you explain? Thanks!

      So NH3 has a pka of 38 (remember: the lower the pka, the BETTER the acid). So NH3 is a weak acid, which means NH2- (the conjugate base of NH3 is a strong base). H20 has a pka of 16 (a much better acid relative to NH3), so its conjugate base OH- is not as strong of a base than NH2-
