Document Summary

E+ - carbocaion / + of c-x. Lg displaced halides / - of c-x. Subsituion reacion -> nu atacking the e+ (w/ displacement of the lg) Rxn rate -> [c] of rea|prd / ime. Determining order measure rate at varying [c] pf a &| b. Aa + bb -> cc + dd. Rate =k[a]1[b]0 ; order = 1+0 =1; 2[a] -> double rate; Sn1 broken i/t 2 steps bond cleavage to lg / formaion with nu. Sn2 one step simultaneous bond breakage / formaion. Rate =k[a]1[b]1 ; order = 1+1 =2; 2[a] -> double rate; Intermediate (w/ a lifeime) v. transiion state (just prg) Lewis b (lone pair; illed mo) -> lewis a (empty) Lewis base donate e- density to the * of the lewis acid, weakening the bond. Back atack nu must approach from the opposite of c-lg. Diferent priority s/r may not switch. Nu -> - homo -> sp3 on s. (dia/n) addiion from l/r 50:50 prd.
