Question

1. Find the product(s) of the following reaction: 1. Br2, light 2. NaOEt, EtOH 3. HBr, ROOR I

Answer 1

Brz in presence of light shows free radical mechanism. Brzar Br -Br light 2 Bir free radical Bro reacts with the given substrate at two different positions - one. + Br (Minor) +HBR 1 carbon radical very unstable thos +Br thor zo benzylic radical very much stable, (Major) resonance stabilization the free radical. of So, (Major) + (Minor) e. C By Br Br (major) (Minor)

BP So, Ar I s. Bre, light Majon Minor Both these products on reaction with Nadet, EtOH (strong same alkene. base) gives Đ 2. Naset, EtoH Ни (Mojos alkene H Soet Etot alkene So, In s second step we get alkene Hor, in presence of ROOR, shows free radical mechanism. As follows ROOR 2RO dissociation Rohor ROH + Br + во OR Bro (Major) 20 Benzylic radical very much stable by resonance, as shown previously Br (Minor) I carbon radical unstable

Br So, +H Br (another molecule of Hor во So, Br + H 1er (another HBP FDZHD (Major) (Major) molecule Bp Bor H adoasut Н Bro .It another Hor Minor molecule Br So, Br 1. Bry, light + (Major) (Minor) Terhoft, EtOH Br sr HBBR + 3. Abs, ROOR (alkene) (Major) (Minor) final products If you like the solution, please give a thumbs up. Thank you.
