For each of the following, choose the best answer (give the letter).

 

(i) Which one has the smaller heat of hydrogenation: (a) 1-methylcyclohexene or (b) 3-methylcyclohexene?

(ii) Which one has the larger heat of combustion: (a) (E)-cyclononene or (b) (Z)-cyclononene?

(iii) Which one is a concerted reaction: (a) acid-catalyzed dehydration of an alcohol; (b) reaction of a tertiary alkyl chloride

with potassium tert-butoxide; or (c) addition of Cl 2 to an alkene?

(iv) Which one is thermodynamically more stable: (a) isobutyl radical or (b) tert-butyl radical?

(v) Which one is the rate law for an E2 reaction of an alkyl halide: (a) rate = k[RX] or (b) rate = k[RX][base]?
