I was wondering if someone could help me with problems on my
test my teacher allows me to correct the wrong ones then give them
back for half credit. Along with the correct answer for each I’d
like to know why the answer I chose is wrong what is the correct
answer and why it is the correct answer. The marked red problems
are the incorrect problems.

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...
