Can i get help with this problem 

A mechanism for this process is shown below:
H
0=c=o:
In the first step, the Grignard reagent attacks the electrophilic center of carbon dioxide, generating a
carboxylate ion. Treating the carboxylate ion with a proton source affords the carboxylic acid. These
two steps occur separately, as the proton source is not compatible with the Grignard reagent and can
only be introduced after the Grignard reaction is complete. This reaction provides us with another
two-step process for converting an alkyl (or vinyl or aryl) halide to a carboxylic acid.
