![SN2 Trap: Why (R) Doesnt Always Invert to (S)
Think SN2 always inverts R/S configuration? Dont fall for the (R) to (R) trap on your midterm! If youve been taught the Golden Rule that SN2 must flip between R/S, this video is required viewing.
Were dissecting a textbook lie utilizing a 1970s breakthrough from the H.C. Brown lab. Ill show you exactly how an (R) reactant can produce an (R) product through a perfectly standard SN2 mechanism, WITHOUT breaking a single rule.

What youll master in this gotcha question breakdown:
• The CIP Trap: Why (R) to (R) isnt a mechanism failure, but a priority change.
• Super-Hydride Logic: Dissection lithium triethylborohydride (LiEt3BH) to see why its the surgical strike of nucleophiles.
• The Spatial Literacy Test: Using 3D molecular models to see the backside attack when the 2D drawings fail you.
