a student was asked to identify an unknown hydrate by following the procedure described in this module. after heating
The boiling point of propylamine, CH3CH2CH2NH3, is 48 °C while that for its isomer trimethylamine, (CH3)3N, is only 3 °C. Explain the difference on the basis of the intermolecular forces
As conjugated dyes get longer, two effects compete. The Equation, ?= 8mcL^2/h(2ni+1) indicates that as ni increases, the absorption wavelength should decrease, but as L increases, the absorption wavelength should increase. Which one wins and why?
The product in the 3rd step of this multi-step synthesis, p-aminobenzoic acid (PABA), was a common ingredient in sunscreen lotions. PABA is such an effective sunscreen due to the many resonance structures that can be drawn for this molecule.
