CHEM263 Midterm: CHEM 263 Exam 1
Document Summary
Circle those of the following structures which you would expect to show aromaticity. Draw structures for which names are given, and name the given structures by any accepted system: m-bromonitrobenzene. Draw the structure of the major organic product(s) of the following reactions. Show only the monobrominated products for a) and b) and the mononitrated products for c) and d) H3c ch3: list the reagents which will accomplish the following transformations. In all cases, more than one step is required. a) Ch2: bh3, h2o2, oh-, 0oc b) c) d) Nh2nh2 or sn/hcl: kmno4, h2so4, hno3, h2so4, febr3, br2, mg, co2, h3o+ Cooh: rank the following compounds according to their reactivitiy towards electrophilic aromatic substitution by numbering them from 1 to 4 where 1 is the most reactive and 4 the least reactive. (4 pts) 1: (4 pts) chlorobenzene is less reactive towards electrophilic aromatic substitution than benzene, but incoming substituents are directed into ortho and para positions.
