3. The nucleophilicty of ionic nucleophiles (like SH- or alkoxides) can change dramatically from polar protic solvents to polar aprotic solvents. On the other hand, the nucleophilicty of neutral, molecular nucleophiles (like H2S, or neutral alcohols ROH) remains relatively constant in both types of solvent. Explain these differences using examples of both types of nucleophiles interacting with common protic and aprotic solvents.

Reaction Stoichiometry Most hydrocarbons are highly combustible. That is, they can react spontaneously with oxygen (O2), forming the products carbon dioxide, (CO2), and water, (H2O). What mass of water will be produced by the complete combustion of 3.38 g of methyl hexane (CH3C6H13)?

4 Show two different combinations of phosphorous ylides and aldehydes or ketones that would react to make the following compounds. a) b) 5 For each of the phosphorous ylides in Question 5, show how it would bE made from an alkyl halide and triphenylphosphine. Note any reaction that may not work well. Phosphines like triphenylphosphine are relatively good, relatively non-basic nucleophiles. Because a phosphorous atom is large, the three phenyl groups are only a minor steric issue

Nitrogen and oxygen can react to form nitrogen monoxide. Write a balanced chemical equation for this equilibrium reaction (including states of matter). -Start this reaction by adding 0.012 moles of both nitrogen and oxygen to a 500-mL flask. If Kc = 4.35x10-31, what are the equilibrium concentrations of my three chemicals?
