Text Solution

Verified by Experts

The correct Answer is:
D
I. `R-oversetunderset(||)(O)(C ) -CH_3 overset(LiAlH_4)(to) Rundersetoverset(|)(OH)(C )HCH_3`
II. `overset(P//HI)(to)RCH_2CH_3`
III. `overset(Zn(Hg)//conc.HCl)(to) RCH_2CH_3` (Clemmensen)
IV. `overset(N_2H_4//C_2H_5overset(-+)(ON)a)(to)RCH_2CH_3` (Wolff-kishner)
Thus , II, III and IV.
