Grignard Reactions

[Eiteiou]

Question: Which of the following types of functional groups react with Grignard reagents: alkenes; terminal alkynes; non-terminal alkynes; alcohols; alkanes; tertiary amines; secondary amines?

 

I know that grignard reagents are strong bases and nucleophiles, and so they will react with alcohols, terminal alkynes, and secondary amines definitely. Alkenes, alkanes, and non-terminal alkynes will not react, right? The one I'm not sure about is the tertiary amine...I have not seen an example of a grignard reagent reacting with one but I don't see why not...too crowded, charge distribution, I'm not sure??

 

Is my thinking correct on this??

Thanks!
