None of these choices
2)For the following reaction sequence (it is not necessary to understand the chemistry) what significant change(s) would be expected by IR (ignoring C-H absorptions)?
None of these choices.
3)For the functional group(s) on the following molecule, what characteristic IR absorption(s) would be expected (ignoring C-H absorptions)?
None of these choices.
Please provide explanations! thank you in advanced.
A peak around 3300 cm-1 would disappear and nothing new would appear. OH pCCExplanation / Answer
1. A new peak around 1710 cm-1 would appear and a peak around 3300 cm-1 would disappear.
In IR -oH gives absorbtion at 3300 cm-1 , In reaction -OH converts in to -C=O gives absorbtion at 1710 cm-1.
2. A)A peak around 1710 cm-1 would disappear and a new peak around 3300-3500 cm-1 would appear.
3. peaks around 1650 and 3300 cm-1
