Q1: A bulky base would remove hydrogen from the least hindered carbon atom and less substituted alkene is the major product i.e. zaitsev product.
While a small base would remove hydrogen atom from the more hindered carbon atom because that would result into a more stable product i.e. Hoffman product.
Q2:
Moles of sodium methoxide = 25.0×10-3L × 0.100mol/L = 2.5×10-3 mol
Moles of 2-bromobutane = 25.0g/137.02g/mol = 1.825×10-2
Sodium methoxide is the limiting reagent.
Moles of the product = 2.5×10-3 mol
Q5: sodium methoxide shows elimination reaction (E2 mechanism) with 2-bromobutane . The reaction proceed in a single step .

please answer the prelab excercise:) I tried doing it but I did not get very far Experiment 7: Grignard Reaction. Introduction Discovered by French chemist Victor Grignard, the reaction that now bears his name is an example of the preparation of an organometallic reagent. In this lab, phenylmagnesium bromide is the Grignard of interest, and it will be added to an aldehyde to produce an alcohol. Lab Objectives 1. To study organometallic reagents in general. benzophenone. 2. To prepare phenylmagnesium...
