Question

After running the reaction shown in question 6, the product is purified by recrystallization with methanol. A 1H NMR is run with the following results:

3.42 (3H, s), 3.97 (1H, s), 4.00 (3H, s), 7.68 (1H, dd), 8.38 (1H, d), 8.43 (1H, d), 8.86 (1H, s)

What conclusions can be made?

A) The NMR data provides evidence that the methanol was not completely evaporated from the sample.

B) The NMR data is consistent with what would be expected for the pure product.

C) The NMR data is most consistent with the starting material, the product must not have formed.

D) The NMR data shows evidence for the presence of both the starting material and product.

A) The NMR data provides evidence that the methanol was not completely evaporated from the sample.

C) The NMR data is most consistent with the starting material, the product must not have formed.

D) The NMR data shows evidence for the presence of both the starting material and product.

Explanation / Answer

option (d), the given NMR data shows the molecule belongs to Imidazoquinazoline derivatives
