The alkylation of 1‚4-dimethoxybenzene is very favorable because of the presence of two methoxy groups. The groups act as activators to electrophilic aromatic substitution because of their ability to donate electrons through resonance. This enhanced activation helps favor the initial substitution. After this‚ the ring has two methoxy groups and an alkyl group attached to it. The addition of the alkyl group further activate the ring for another electrophilic aromatic substitution. The addition of

Lab Questions: Unit 1 Autopsy of a Crime Scene 1. Which technique is the best choice when blood is found at a crime scene? In the genetics laboratory‚ who is one individual that contributed to modern genetic analysis? What did this person contribute? - The DNA Analysis Technique is the best choice because no two individuals have the same DNA.

In this lab we are going to be observing the decomposition of piglets over a month’s time. There are theory questions that have been given to us before and after the lab. We look back at our original theory to see where we went wrong‚ and then correct it. The lab was disgusting‚ surprising‚ and very interesting. The first questioned to be answered is which piglet decomposes faster‚ a piglet that is in its natural state‚ that is burnt‚ that is buried‚ and that is buried in a wooden box? With

FOUNDATION IN SCIENCE INTRODUCTION TO PRACTICAL ORGANIC CHEMISTRY – MAKING AND PURIFYING ORGANIC COMPOUNDS Stage 1 – Deciding how much reagent to use Most organic reactions do not go to completion; most reach an equilibrium position with significant quantities of reactants still remaining. In addition‚ separating the desired product from the rest of the reaction mixture‚ and then purifying it‚ will result in the loss of more of the product. The amount of product obtained expressed as a percentage
