(a)
Interpretation:
The 1H and 19F spectra of FC2H should be predicted.
Concept introduction:
Spin-spin coupling is a phenomenon which is caused by the spin coupling between two chemically different nuclei which are NMR active. This effect is indicated through peak splitting in NMR spectra. Coupling constant is a measure of interactions between NMR active nuclei.

Interpretation:
The 1H and 19F spectra of CF3CH3 should be predicted.

- Blocking Group are use to put 2 large sterically repulsive group ortho. Show the correct sequence toconnect the reagent to product with the highest yield possible. * see image **NOTE: The compound on the left is the starting point, and the compound on the right is the final product. Please show the steps in between to get from start to final, please. These are not two different compounds that need to be worked.arrow_forwardI dont understand this.arrow_forwardCan you please explain this prooblem to me, show me how the conjugation is added, did I add them in the correct places and if so please show me. Thanks!arrow_forward
- Basic strength of organic bases.arrow_forwardNucleophilic Aromatic Substitution: What is the product of the reaction? What is the name of the intermediate complex? *See imagearrow_forwardPredict the final product. If 2 products are made, list which should be “major” and “minor” *see attachedarrow_forward
- Nucleophilic Aromatic Substitution: What is the product of the reaction? *see imagearrow_forwardShow the correct sequence to connect the reagent to product. * see imagearrow_forwardThe answer here says that F and K have a singlet and a doublet. The singlet and doublet are referring to the H's 1 carbon away from the carbon attached to the OH. Why don't the H's two carbons away, the ones on the cyclohexane ring, cause more peaks on the signal?arrow_forward
