Provide methods for synthesizing the following compounds using only a Grignard reaction, plus any necessary workup. In each case the Grignard reagent, butyl magnesium bromide, must be used in the synthesis. Express these syntheses in the form of balanced equations, using structural formulae, showing all reagents and any specific conditions required. A) Pentanoic Acid B) 1-Hexanol C) Butane D) 5-Methyl-5-nonanol E) 5-Methyl-5-nonanol (different reaction from d)
