NMR spectrum; THIS QUESTION IS FOR OTA 104318

In the Garden Cress problem you helped me with (PC20042), you were right when you said that the NMR given was incorrect. My questions are: what would the question look like for which this NMR can be used? What would the IR and mass spectrum look like? What do I need to recognize on each spectrum to answer the same questions g ...continues

NMR spectra (Garden Cress Continued) For OTA 104318

One more question and I think I am done. Refering back to the Garden Cress Problem. What should the NMR look like? Please let me know If I need to send the question again (PC20042). Thank you, you have been a great help!

Aldol condensation: why must aldehyde contain none of corresponding acid?

In the aldol condensation w/ benzaldehyde + acetone (NaOH, ethanol) --> dibenzalacetone Why is it essential that the aldehyde component contain none of the corresponding acid?

Predict the product of the crossed Cannizzaro reaction

[Question] [Predict the product of crossed Cannizzaro reaction between formaldehyde and p-anisaldehyde (4-methoxybenzaldehyde).] In excess formaldehyde, the aromatic aldehyde is reduced to a primary alcohol in high yield.

mechanism for internal Cannizzaro reaction

Show me a mechanism for this internal Cannizzaro reaction: phthalaldehyde ---> 2-(hydroxymethyl)benzoic acid

alkenes

"When 2-butene reacts with hydrogen chloride gas, only one product is detected. When 1-butene reacts similarly, two products are usually found. Explain this." I know that 2-butene + HCl produces 2-chlorobutane. I looked up Markovnikoff's rule to try to help me, and I think that one of the products of 1-butene + HCl is also ...continues
