Based on the above FTIR spectrum, does dimedone exist as the diketo or keto-enol tautomer in the solid state? How can you tell? (Hint: Look up the X-ray Crystal structure of the compound if you need to double check your answer.)

Answer 1

Answer: In given IR- spectrum absence of Sroong broad band above 3000 cm - indicates that absence of hydroxyl(-OH) group.other band at 29 cm is of spe Ich stretching and also absence of band 1600-1680 cml indicate that absence 07 sp?'garboni ei care . Thus compound must be present in diketo form. - The bands at nis im is caracteristic z byclohexanone and other band near to usloml and 1734com indicates towo carbonyl group are present. . Thus dimedonė į must be exist is dikelo forro in solid state a n d CF 3 is solid.
