WebMay 5, 2016 · 1. Introduction In 1945 Robert Burns Woodward gave certain rules for correlating λ structure. In 1959 Louis Frederick Fieser modified these rules with more experimental data, and the modified rule is known as Woodwar and λmax for a given structure by relating the position and degree of substitution of chromophore. 2. WebFischer projections are a way to represent three-dimensional molecules in two dimensions. By following specific rules for drawing these projections, one can depict complex … WebAfter giving a set of instructions to your kids, pause for 3-7 seconds to allow their brain to process and apply the information. Research shows kids are more likely to follow directions if you give them “wait time” or a hearty pause. As adults, we are used to processing information much quicker, but kids…they take time. biography of noah in the bible
