Which statements are true for SN2 reactions of haloalkanes? (a) Both the haloalkane and the nucleophile are involved in the transition state. (b) The reaction proceeds with inversion of configuration at the substitution center. (c) The reaction proceeds with retention of optical activity. (d) The order of reactivity is 3° > 2° > 1° > methyl. (e) The nucleophile must have an unshared pair of electrons and bear a negative charge. (f) The greater the nucleophilicity of the nucleophile, the...

Question about SN1 and SN2 reactions. In my lab we prepared 1-bromobutane from 1-butanol (SN2) and 2-chloro-2-methylbutane from 2-methyl-2-butanol (SN1). I don't undetstand the following questions: 1. Why did we heat the SN2 reaction but not the SN1 reaction? 2. What was the purpose of performing a simple distillation on both reactions? What were you isolating your products from? 3. What was the purpose of washing both of oyur reaction mixtures with brine (saturated sodium chloride)?

What are the basic differences between SNAr reaction with SN1 and SN2 reactions?
