The answer to 3 problems
1. The Antisymetric -CH2-CO-O Stretching Vibraton in carbolic acid is heavily mixed with in plane bending mode of theO_H group. In alchol these two vibrations seldom show evidence of mehanical coupling. Explain
2. Conjugation of the functional group in alkyl socyanates has little impact on the antisymmetric -N=O stretching vibration located near 2770/cm . Explain.
3. The CH stretching mode of chloroform CHCL3) which occurs at 3022/cm is one of the rare exceptions to the 3000/cm rule. What is the rule? Suggest an explanation for this exception.
