Tert-butyl Memes

The drama in this chemical relationship is off the charts! That hydroxide ion (HO - ) is desperately trying to perform an elimination reaction with tert-butyl chloride, but the bulky methyl groups are like bouncers at an exclusive molecular club saying "NOPE!" This is classic steric hindrance - where those chunky methyl groups physically block the nucleophile from attacking. The molecule's panicked "AAAAAAAAHHHHH" is basically what your organic chemistry professor hears internally whenever students mix up SN1 and SN2 reactions. Chemistry's version of "it's not you, it's my bulky molecular structure."
