bet you pick E2 for a 3° bromide in ethanol. 👇 search
bet you pick E2 for a 3° bromide in ethanol. 👇 search "inkling orgo" on the App Store or go to tryinkling.app E1 or E2, how to actually tell, for orgo 1 midterm 2 substitution and elimination. step 1, look at the base: a strong base like NaOEt, NaOH or t-BuOK means E2, one step where the base takes the H next door while the bromide leaves, and the rate depends on both the halide and the base. a weak base or neutral solvent like ethanol or water means the E1 path: the bromide leaves first to make a carbocation, then a weak base takes an H, and the rate depends on the halide only. step 2, look at the carbon: a 3° halide can go either way, a 2° can too, and a 1° can only do E2 (with a bulky base like t-BuOK) because a primary carbocation is too unstable. worked example, 2-bromo-2-methylbutane: with NaOEt in ethanol it is E2 and the major product is 2-methylbut-2-ene (Zaitsev), with 2-methylbut-1-ene as the minor one. the same bromide in hot ethanol with no strong base goes E1 and gives mostly 2-methylbut-2-ene again, with the SN1 ether competing. slide 5 is the 3 traps 🧐 a strong base on a 3° halide is E2, not E1, because the base never waits for a carbocation. E1 never comes alone, SN1 shares the first step and heat is what tips it toward E1. and on a ring, E2 needs the leaving group and the H both axial (anti), so a ring flip can decide it. the stuff that loses points on midterm 2 👀 saved this? practice quizzes like it in the app which one do you mix up, E1 or E2? 👇 #ochem #organicchemistry #e2 #studytok #examprep
