Which of the following reactions favor formation of the products? Recall that the equilibrium favors formation of the weaker acid.

Which is more reactive, an organolithium compound or an organosodium compound? Explain your answer.

What organometallic compound is formed from the reaction of excess methylmagnesium chloride and GaCl₃?

Muscalure is the sex attractant of the common housefly. Flies are lured to traps filled with bait that contain muscalure and an insecticide. Eating the bait is fatal. How could you synthesize muscalure using 1-bromopentane as one of the starting materials?

The Stille reaction is similar to the Suzuki reaction. It replaces the alkenyl-organoboron compound of the Suzuki reaction with an alkenyl-organotin compound. (R is an alkyl group such as methyl or butyl.) Unlike the alkenyl-organoboron compound that always has a trans configuration, the alkenyl-organotin compound can have a cis configuration. What is the product of the Stille reaction shown here?
