Question

2. Give the structure of the major product formed on the following reactions. a) Sodium ethoxide and benzyl bromide b) 2-phenylpropene and hydrogen chloride CCl ight d) CI e) 0片 H C 8) h) Na, NH CHyOH CH CH 3. Write the sten hy sten reaction

Answer 1

Br OEt NaOEt benzyl bromide major product Explanati on: NaOEt is a strong nucleophile which gives SN2 substitution reaction with alkyl hali de. Cl Cl 2-phenylpropene Explanati on: Addition of HCl to alkene produces a stable carbocati on which on further attack with Cl- produces alkyl hali de as product.

O2N C-CH3 light product Explanati on: Br2 in presence of light produces bromination at benzylic position HBr CCH2 -CH3 product Expl anati on: Addition of HBr to alkene produces alkyl halide as product.
