(encz) | structural formula, n: |
structural formula
(gcide) | Formula \For"mu*la\, n.; pl. E. Formulas, L. Formul[ae].
[L., dim. of forma form, model. SeeForm, n.]
1. A prescribed or set form; an established rule; a fixed or
conventional method in which anything is to be done,
arranged, or said.
[1913 Webster]
2. (Eccl.) A written confession of faith; a formal statement
of foctrines.
[1913 Webster]
3. (Math.) A rule or principle expressed in algebraic
language; as, the binominal formula.
[1913 Webster]
4. (Med.) A prescription or recipe for the preparation of a
medicinal compound.
[1913 Webster]
5. (Chem.) A symbolic expression (by means of letters,
figures, etc.) of the constituents or constitution of a
compound.
[1913 Webster]
Note: Chemical formul[ae] consist of the abbreviations of the
names of the elements, with a small figure at the lower
right hand, to denote the number of atoms of each
element contained.
[1913 Webster]
Empirical formula (Chem.), an expression which gives the
simple proportion of the constituents; as, the empirical
formula of acetic acid is C2H4O2.
Graphic formula, Rational formula (Chem.), an expression
of the constitution, and in a limited sense of the
structure, of a compound, by the grouping of its atoms or
radicals; as, a rational formula of acetic acid is
CH3.(C:O).OH; -- called also structural formula,
constitutional formula, etc. See also the formula of
Benzene nucleus, under Benzene.
Molecular formula (Chem.), a formula indicating the
supposed molecular constitution of a compound.
[1913 Webster] |
Structural formula
(gcide) | Structural formula \Struc"tur*al form"u*la\ (Chem.)
a symbolic representation of the structure of one molecule of
a chemical compound, showing the attachments of the atoms to
each other, and representing their arrangement in space; the
spatial representation is symbolic and approximate, and it
may or may not depict the stereochemical relations of the
bonds. Distinguished from empirical formula. See also
Rational formula, under Formula.
