In proton NMR spectroscopy, the shift of the proton is affected by the geometry of the carbon to which it is bonded. • Predict where a proton bonded to an sp2 carbon would show up.
• Predict where a proton bonded to an sp3 carbon would show up.

Mike and mitchell decide to have a foot race. they mark off a stretch of 100 yards, and recruit cindy to work the stopwatch. after running the race and looking at the results, cindy declared that mitchell was the fastest. so how did the boys times compare?

Which theory was contradicted by experiments with the photoelectric effect? light spreads out after it passes through a small opening. as soon as light strikes metal, electrons will be ejected. visible light, regardless of color, will cause the ejection of electrons when striking metal. the kinetic energy of ejected electrons depends on the frequency of light that strikes the metal.

Ab c or d ? i’m not sure what the answer is
