[graded] consider these two reactions. krel is the "relative rate constant," a quantitative measure of how fast reactions go relative to each other. bu ncn is a salt: ch2cl2 solvent oso, ch, + bu ncn cn kg = 0.1 cen ch, cl, solvent oso, ch, + bu, non kred= t o an bu = butyl (4-carbon) chain (a) why do you think the cyanide anion is introduced as a salt with bu4nrather than as a salt with, say, nat ? (b) explain the difference in reaction rates. in other words, why does the first reaction proceed so much more slowly than the second reaction? (they're done at the same temperature and with the same concentrations of reagents.)

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
