Electropositive

Electropositive

1. (Science: chemistry, physics) Of such a nature relatively to some other associated body or bodies, as to tend to the negative pole of a voltaic battery, in electrolysis, while the associated body tends to the positive pole.

The converse or correlative of electronegative. Usually refers to an element whose atoms tend to lose electrons; e.g., sodium, potassium, calcium.

An element that is electropositive in one compound may be electronegative in another, and vice versa.

2. (Science: chemistry) Hence: Positive; metallic; basic; distinguished from negative, nonmetallic, or acid.

(Science: chemistry) a body which passes to the negative pole in electrolysis.

Which Molecule is a Better Acid?

... thing possible) it would be the second one: inductive effect - OH pulls electrons away from the carbon, the carbon on the carboxyl becomes more electropositive. But i think that there wouldn't be much difference anyway - I mean, the conjugate base is stabilized by resonance in both, the inductive ...
