Semantic Scholar extracted view of "Estimation of Ortho-, Pyro-, Meta-, and Polyphosphates in Presence of One Another" by Loren T. Jones Answer (1 of 2): When describing acids, ortho and meta have a different meaning than these same prefixes have when describing benzene derivatives. For Naming as ortho acid, that acid should contain minimum three hydrogen atoms. the combining form that means straight upright Escuela de Ingeniera. Condensed phosphates (also called meta, pyro, or polyphosphates) are two or more orthophosphate groups that are linked together. This is because of two reasons: Talking about the first one, Due to presence of nitro group on ortho position, the -COOH group bends out of the plane of the ring due to steric hindrance. The correlation for a natural log fit for all groups except carboxylic acid and electron donating groups (ERG) is good, with R 2 values of 0.939, 0.9282 and 0.9018 for ortho, meta and para respectively, corresponding to average absolute percentage deviations of 124, 122 and 125% from the experimental values respectively.
