What do Grignard reagents attack?

Answer 1

Dry ice, ethylene oxide, ketones, and aldehydes.

The optimal method for producing carboxylic acid is still to apply a Grignard reagent onto dry ice (and to stand well back). This process lengthens the carbon chain by one unit, and the Grignard's action on ethylene oxide results in a magnesium alkoxide by increasing the carbon chain by two units.

You are aware, of course, of how Grignards react with aldehydes and ketones to produce substituted alcohols.

Grignard reagents are typically avoided because they are intolerant of water and alcohol.

Grignard reagents typically react with electrophiles, such as carbonyl compounds (aldehydes, ketones, esters), epoxides, and alkyl halides.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
