Formalin and methanal are both synonymous with formaldehyde

If 2-butanol is dehydrated in the presence of a strong acid, and the resulting product is reacted with ozone followed by water, what product(s) would you expect from this reaction?

Draw a diagrammatic reaction mechanism sequence (not reaction equation) for the reaction of RuCl3 with triphenylphosphine and aqueous methanal in refluxing 2 methoxyethanol?

Give the systematic name (with correct spelling and punctuation, i.e. 2-propanol) of the product obtained from the addition of methyl lithium (CH₃Li) to methanal, followed by the addition of water.
