LATERAL CHAIN THEORY 51 



ring with a central nucleus of C 6 with lateral chains of H. con- 

 necting each atom of C. 



If one of these lateral chains H. is supplanted by the acid radical 

 COOH. the benzol is converted into benzole acid and its formula is 

 represented thus: 



O

 C OH

BENZOIC ACID. 



If to this acid radical of the benzoic ring, sodium hydroxid unites, 

 supplanting an H in the OH of this radical, we have, instead of 

 benzoic acid, benzoate of soda.

BENZOATE OF SODA. 



It is thought that as the soda is brought in contact with the central 

 nucleus of the benzol ring, so food stuffs unite with the central body 

 of the cell molecule in the organism and nourish it.
