Identify all acidic sites in the starting materials (there are 3 but only one is useful) then provide a complete
mechanism for the reaction (LDA = lithium diisopropylamine = strong base). You are allowed to use some
acid for the workup, i. e. the very last step is a protonation to give you the product. Note in the product that a
bond in front crosses the bond behind. The bond behind is not broken - its deliberately drawn like that to
emphasise the 3D nature of the product.

Forests and meadows are often cut down to make way for farms or large number of new homes. what are some of the elements of ecosystems that are lost when plants in these areas are removed?

What will most likely happen when two bromine atoms bond together?

Sulfur dioxide and oxygen react to form sulfur trioxide during one of the key steps in sulfuric acid synthesis. an industrial chemist studying this reaction fills a 25.0l tank with 4.5 mol of sulfur dioxide gas and 4.5 mol of oxygen gas at 30.°c. he then raises the temperature, and when the mixture has come to equilibrium measures the amount of sulfur trioxide gas to be 1.4 mol. calculate the concentration equilibrium constant for the reaction of sulfur dioxide and oxygen at the final temperature of the mixture. round your answer to 2 significant digits.
