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

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
