oh    音标拼音: ['o]
int. (表示惊讶,恐怖,赞叹)哦!

OH
n 1: a midwestern state in north central United States in the
Great Lakes region [synonym: {Ohio}, {Buckeye State}, {OH}]

Oh \Oh\ ([=o]), interj. [See {O}, interj.]
An exclamation expressing various emotions, according to the
tone and manner, especially surprise, pain, sorrow, anxiety,
or a wish. See the Note under {O}.
[1913 Webster]


-ol \-ol\ (-[=o]l or -[o^]l) suff. [From alcohol.] (Chem.)
A suffix denoting that the substance in the name of which it
appears belongs to the series of alcohols or hydroxyl
derivatives, as ethanol, carbinol, phenol, glycerol, etc.
Such compounds contain the hydroxy radical ({-OH}).
[1913 Webster PJC]


molecular formula \mo*lec"u*lar form"u*la\, n. (Chem.)
An expression representing the composition of elements in a
chemical substance, commonly consisting of a series of
letters and numbers comprising the atomic symbols of each
element present in a compound followed by the number of atoms
of that element present in one molecule of the substance.
Thus the molecular formula for common alcohol (ethyl alcohol)
is {C2H6O}, meaning that each molecule contains two carbon
atoms, six hydrogen atoms, and one oxygen atom. The molecular
formula may be written to provide some indication of the
actual structure of the molecule, in which case structural
units may be written separately. Thus, ethyl alcohol can also
be written as {CH3.CH2.OH} or {CH3-CH2-OH}, in which the
period or dash between functional groups indicates a single
bond between the principle atoms of each group. This formula
shows that in ethyl alcohol, the carbon of a methyl group
({CH3-}) is attached to the carbon of a methylene group
({-CH2-}), which is attached to the oxygen of a hydroxyl
group ({-OH}). A {structural formula} is a graphical
depiction of the relative positions of atoms in a molecule,
and may be very complicated.
[PJC]
