Question

() The I.R. frequency of co group in dichloro acetone increases as compared to acetone
because
(a) -I effect of Cl-atom increases double bond character and absorption occurs at higher
wave number
(b) +1 effect of Cl atom increases double bond character and absorption occurs at higher
wave numbers
(c)-I effect of Ci atom decreases double bond character and absorption occurs at higher
wave number.
(d) None of these

​

Answer 1

Answer:

good morning friends

Answer 2

-1 effect of Cl atom increases double-bond character and absorption occurs at higher wavenumbers.

Explanation:

Hooke’s  Law (section 16.04) tells us that differences in bond order (single versus double bond) or  differences in the masses of the bonded atoms (C–H versus C–O) influence the stretching  frequency, but it says nothing about the absorption intensity.
