Achiral amine a having the r configuration undergoes hofmann elimination to form an alkene b as the major product. b is oxidatively cleaved with ozone, followed by ch3sch3, to form ch2═o and ch3ch2ch2cho. what are the structures of a and b? indicate stereochemistry where appropriate.

For each of the following types of reactions, write a general reaction formula in the symbolic form—for example, a + b → ab. single-displacement double-displacement synthesis decomposition
