Practice Problem: Four-Reaction Pathway

The video tutorial explains a sequence of reactions starting with benzene. It covers electrophilic aromatic substitution to brominate benzene, the formation of a Grignard reagent using magnesium, and the reaction of this reagent with CO2 to produce benzoic acid. Finally, it discusses the reduction of benzoic acid to a primary alcohol using lithium aluminum hydride.

What is the first reaction that involves benzene and bromine, and what type of reaction is it?

Explain the role of magnesium in the second reaction and what it helps to generate.

Describe how Grignard reagents interact with carbonyl compounds, specifically in the context of CO2.

What is the final product obtained after the reduction with lithium aluminum hydride?

Summarize the sequence of reactions starting from benzene to the final product.
