Question

What does Grignard do?

Answer 1

See this [old answer.](https://socratic.org/questions/what-are-grignard-reactions#305964)

Explanation:

Grignard reagents allow `C-C` bond formation straightforwardly and routinely. This is significant because in organic chemistry there are very few means to make `C-C` bonds, and the Grignard reaction is undoubtedly the premier means to make such `C-C` bonds.
