Question

The following reaction is an example of: a substitution reaction a rearrangement reaction an addition reaction an elimination reaction In the course of the reduction of benzophenone to benahydrol using NaBH_2, what change should be observed in the infra-red spectrum. The 3500 cm^-1 peak diminishes and the 1700 cm^-1 peak increases. The 1700 cm^-1 peak diminishes and the 3500 cm^-1 peak increases. The 1600 cm^-1 peak diminishes and the 3000 cm^-1 peak increases, The 3000 cm^-1 peak diminishes and the 1600 cm^-1 peak increases. What is the formal charge on the chlorine atom? +1 0 -1 +2

Explanation / Answer

9. during the reaction H+ ion shifting .so that , it is a reaarangement reaction

answer: b

10. answer: b

because , ketone group is appeared at 1700 cm-1 and it converts into -OH group appears at 3500 cm-1

11. fromalcharg = V - 1/2s+L

                = 7-(1/2*4+4)

               = +1

       answer: a
