Why is #CO_2# an electrophile?

The carbon centre is bound to 2 strongly electronegative atoms, which tend to make the carbon centre highly electrophilic.


Carbon dioxide, as dry ice, is actually used a lot in organic synthesis. Addition of Grignard reagent, #R-MgX#, to dry ice results in a carboxylate salt that is 1 carbon longer than the hydrocarbyl chain #R#:

#R-MgX + CO_2(s) rarr RC(=O)O^(-)""^(+)MgX#

Normally you would pour your Grignard solution directly onto dry ice pellets, and take a step back.
