Question:

Would an aromatic proton show up further downfield on a Proton Nuclear Magnetic Resonance (NMR) Spectrum than an aldehyde ?

Inactive
Ashton C.
Answer:

The aldehyde would show up further downfield because its shift is around 10-12ppm while an aromatic proton shows up around 6-8ppm. The higher the number/more to the left on the spectrum the more downfield a proton is.

Answer:

The correct answer is D. Fluorine because electronegativity increases as you go to the right of the periodic table and also increases as you go up the periodic table.

Question:

Solve for x: 4(x^2 - 1) = -x^2 + 16

Answer:

4(x^2 - 1) = -x^2 + 16 4x^2 - 4 = -x^2 + 16 5x^2 = 20 x^2 = 4 x = 2 First, we use the distributive property and multiply 4 by both the x squared and the negative 1. Second, we add a positive x squared to the left side of the equation in order to get rid of it on the right side. And we also add positive 4 to the right side to eliminate it on the left. Third, we divide by 5 to get the x squared by itself. Lastly, we take the square root of both sides to get x by itself and the final value.
