Determine the theoretical yield (IN GRAMS) for 1-bromobutane if you start with 109 mmol of butanol nd excess acid and sodium bromide. (Note: the stoichiometric relationship between butanol and romobutane is 1:1) Convert the theoretical yield of 1-bromobutane to moles. Convert the moles to mmol. please clearly explain how to do this using the below information with thr correct sig figs Structure for 1-butanol Molecular weight for 1-butanol density for 1-butanol Bonpoint butanol 117.7°C 74.12 gimol 81...

BACKGROUND AND THEORY The Grignard reaction was one of the first organometallic reactions discovered and is still one of the most useful synthetically. By reacting an organohalide (usually a bromide) with magnesium in ethereal solvent, carbon becomes a nucleophile. Grignard reagents are the starting points for the syntheses of many alkanes, primary, secondary, and tertiary alcohols, alkenes, and carboxylic...
