Tertiary amine oxides undergo the Cope elimination, a syn stereoselective elimination reaction involving a planar transition state and a cyclic redistribution of 4n 2 electrons. Draw the structure of the alkene product obtained when (2S,3S)-N, N-dimethyl-3-phenyl-2-butanamine oxide undergoes Cope elimination.

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.
