Document Summary

Hw: pre lab report for ex 1 day 2. Complete reading watching assignments for experiment 3 day 1 (pages 31-33) of lab manual. This week: mixed melting point analysis (you will need to come up with an algothrim to take multiple melting points). Tlc co-spotting will have a middle spot with both unknowns spotted together. Post lab report 1: a copy of notebook pages from ex 1, typed answers of post-lab. Electromagnetic spectrum: shorter wavelength = higher energy, longer wavelength = lower energy. Spectrometers record absorption of em radiation: look at where the wavenumber range is to find out what functional group or bonds are in the spectrum. Ir good for telling what the nature of bonding in the molecule given. Oh peaks will give a broad peak at around 3000. C=o will give a narrow peak at 1700. Nh will give a somewhat broad peak at around 3000-3500.
