What is the correct order of the following inert electrolytes in their ability to increase the degree of dissociation of acetic acid?
a) 0.001 m NaCl
b) 0.001 KBr
c) 0.10 CuCl2
In trans-1,2-dibenzoylethylene, even though the conjugated C=O group frequency coincides directly with the expected C=C stretching fequency, we would not have expected to observe the late stretching mode in the infrared spectum. Why?
