Carbon–carbon bond formation is a key method for building complex organic molecules in chemical synthesis.

A research chemist designs two synthetic pathways, Path A and Path B, to extend the carbon chain of aliphatic compounds by one carbon atom using a carbon-nucleophile:

Organic Synthesis Pathways

Describe both pathways. For each pathway, your answer must include:

  • The identity of the required reagent(s) (reagent 1 and reagent 2).
  • The IUPAC name of the reaction mechanism.
  • A detailed mechanism of the reaction, showing relevant dipoles, lone pairs, and curly arrows.
