Hey, what did you get on your ORGO 2 as you final grade? I am currently taking ORGO 1, and I gotten 95 on the first test, but not so confident in the next test. People told me that ORGO 2 is def. easier, than ORGO 1. Is this true?

Thank you for making this video, kept getting procedure for H-NMR and C-NMR confused, watching you do H-NMR and C-NMR together really helped. this video explained H-NMR and C-NMR better them any I've found on KZfaq, this info will really help me on my Organic chemistry exam tomorrow.

One question remains: Why can you just apply a line of symmetry for the benzine ring of ethylbenzine? I thought that every H-Atom of the molecule has a different signal because there is no symmetry. For example, you say that the H-Atoms at position C2 and C6 are equivalent, as they are equally distanced from the ethyl group. But is the terminal CH3 group of ethyl not closer to the H-Atom at C6 than to that at C2? Wouldn't there be a chemical effect?
