  • C) (i) gives an achiral isomer, (ii) gives a chiral isomer D) two different isomers are formed, but both are chiral 14 Reaction of 1,4-dibromobutane with Mg turnings in ether gives the bis-Grignard reagent, BrMgCH 2 CH 2 CH 2 CH 2 MgBr. Molecules with Several Chirality Centers. A molecule may contain not only one, but several chirality centers. Compounds with n chirality centers may form up to 2 n stereoisomers, as each asymmetric carbon can represent two different absolute configurations.
  • The boxed structure has two stereocenters and is a chiral molecule. The maximum number of stereoisomers that is possible for a given structure, owing to stereocenters, is 2n, where n is the number of stereocenters. If meso structures are possible, then the actual number of stereoisomers will be less than the calculated maximum number.
