CHEM 237B Test # 3 , TA (24) I. True (T) (False (F). The scoring on this section will be + 4 for each correct answer, - 1.5 for each wrong answer. The energy required for heterolytic bond cleavage is independent of solvent. . An increasing proportion of sN1/EI versus SN products at higher temperatures reflects the fact that the energy required for heterolytic bond cleavage decreases as the temperature is raised. . The relative stabilities of carbocation intermediates account for the addition reaction outcomes that correspond to the application of Markovnikov's rule. . Alkyl shifts that lead to rearranged carbon skeletons in elimination products cannot occur when the E2 mechanism applies. . CH~CEC is 1019 times more acidic than CH3CH=CH2 , that makes the alkyne a moderately strong acid like CH3CH20H. - Secondary alkyl bromides do not undergo SN reactions. (13) a. Given the following relative acidities in CH30H - H2Se > H2S > H20, rank the relative nucleophilicities of the following species in DMSO: b) H20, H2S, and HO- a) HO-, HS-, HSe- and NH3 (10) UI.
