Find the final product 'E' CH 2 OH − CH = CH 2 → (ii) NaSO 3 H (i) OsO 4 (A) → KHSO 4 (B) → Zn-Hg / conc . HCl (C) → CCl 4 NBS/hv (D) → (CH 3 ) 2 CuLi (E)

Step-by-step solution

Here the final product E is Butene and the reaction sequence is as follows CH 2 OH − CH   =   CH 2 → (ii)   NaSO 3 H (i)   OsO 4 CH 2 OH − CHOH − CH 2 OH (A) → KHSO 4 CH 2   =   CH − CHO (B) → Zn-Hg   /   conc .   HCl CH 2   =   CH − CH 3 (C) → CCl 4 NBS/hv CH 2   =   CH − CH 2 Br (D) → (CH 3 ) 2 CuLi CH 2   =   CH − CH 2 &#x2212
