Using Ethylene, C2H4, and methyl bromide, CH3Br, as your sole sources of carbon, propose a synthesis for t-BuOH, (CH3)3COH. *the synthesis should take about 7 steps and will include an alkylation and a Grignard reaction. Use one equivalent of methyl bromide for the alkylation step and use the second one to make the Grignard reagent. The substrate in the Grignard reaction will be a carbonyl - make this from your alkyne AFTER alkylation. *show all reactants and intermediates H +2 H H Br -7 steps H₂C H₂C OH CH3

Please show the structure of the missing substances in each of the following acid base equilibria.
Propose a sequence of reactions to prepare the specified target compound from the indicated starting materials. All of the carbon atoms in the target must originate in the specified starting materials. Keeping this restriction in mind, you may use any other organic or inorganic reagents necessary to complete the synthesis. It is only necessary to show the overall transformations involved in your proposed synthesis.
