I need some help with these three questions on organic chemistry bonding:

13. Why it is important that any aldehyde used in Witting reaction be free of carboxylic acid impurities?

14. Explain why the C=C stretching mode gives rise to a rather weak IR band in 1-methylcyclohexane, while in its isomer, methylenecyclohexene, the band is of medium to strong intensity.

15. Predict the major organic product formed in the following reaction: CH3CHzNOz + CHzO ->

13. Why it is important that any aldehyde used in Witting reaction be free of carboxylic acid impurities?

In a wittig reaction, if carboxylic impurities are present they lead to an unwanted side reaction ----namely the Reformatsky reaction, which reduces the yield of the desired ...

Solution Summary

The following posting helps with an organic chemistry problem. This solution provides an explanation on how carboxylic impurities affect the Witting reaction, why the stretching mode gives rise to weak IR bands, and also predicts the major organic product.
