Question

Q1. Products I and II are the major products observed in their respective hydration reactions. What are the identities of I and II? (Look back at the mechanisms and intermediates you form in each case). H30* I) Hg(OAC)2, H2O ii) NaBH4 a) 1 = A; 11 = B b) 1 = B; II = A c) Both I and II = A d) Both I and II = B e) 1 = C; || = A f) I = B; II = C

Answer 1

Que 1. Y "Hg 10 Ac)₂, H₂O. 1 I H2O (i) NaB Hy H₂O having He ions migration I of H Becaus 3° carbo cation is more stable ^ (1) Hg (OAC), H₂O Y 1:11A (11) Na BHYA AO "OAC

Aco ACO O AC DAC two possibility of attack H₂O a and b e when Hg form complex with alkene there general a pautial tue change on caubon. tue change is more stable on go caubon so bath a is more prefroble. HO OH OH Daing AO OAC Nably Hg OAC gt red C-Hg bond option a is correct answer I= A, I = B,
