Use oprically active and racemic where appropriure. Une Holecule per DUX. OH 1.) > Mg-Br 2.) H20 racemic tacchic optically active Cically active cat. H2SO4

Answer 1

solution: OH non o + Bring 2) 11300 racemic. Synthesis: OH O + Bring Ol - racemic. Epoxide under goes ring desired product Grignard carbon atom of epoxide. opening alway in grignard attack less to give substituted R 0 synthesis. optically active. enter This is SN² reaction with optically active inversion of configuration.
