  3. Empirical formula - Wikipedia

    en.wikipedia.org/wiki/Empirical_formula

    Glucose (C 6 H 12 O 6), ribose (C 5 H 10 O 5), Acetic acid (C 2 H 4 O 2), and formaldehyde (CH 2 O) all have different molecular formulas but the same empirical formula: CH 2 O.This is the actual molecular formula for formaldehyde, but acetic acid has double the number of atoms, ribose has five times the number of atoms, and glucose has six times the number of atoms.

    en.wikipedia.org/wiki/Ethyl_acetate

    Ethyl acetate (systematically ethyl ethanoate, commonly abbreviated EtOAc, ETAC or EA) is the organic compound with the formula CH 3 CO 2 CH 2 CH 3, simplified to C 4 H 8 O 2.This flammable, colorless liquid has a characteristic sweet smell (similar to pear drops) and is used in glues, nail polish removers, and the decaffeination process of tea and coffee.

  6. Butyric acid - Wikipedia

    en.wikipedia.org/wiki/Butyric_acid

    Butyric acid (/ ˈ b j uː t ɪ r ɪ k /; from Ancient Greek: βούτῡρον, meaning "butter"), also known under the systematic name butanoic acid, is a straight-chain alkyl carboxylic acid with the chemical formula CH 3 CH 2 CH 2 COOH. It is an oily, colorless liquid with an unpleasant odor. Isobutyric acid (2-methylpropanoic acid) is an ...

  7. Organic acid - Wikipedia

    en.wikipedia.org/wiki/Organic_acid

    The relative stability of the conjugate base of the acid determines its acidity. Other groups can also confer acidity, usually weakly: the thiol group –SH, the enol group, and the phenol group. In biological systems, organic compounds containing these groups are generally referred to as organic acids.

  8. ECW model - Wikipedia

    en.wikipedia.org/wiki/ECW_Model

    As early as 1938, G. N. Lewis pointed out that the relative strength of an acid or base depended upon the base or acid against which it was measured. [1] No single rank order of acid or base strength can predict the energetics of the cross reaction. Consider the following pair of acidbase reactions:. 4F-C 6 H 4 OH + OEt 2 −ΔH = 5.94 kcal/mole

  9. Gutmann–Beckett method - Wikipedia

    en.wikipedia.org/wiki/Gutmann–Beckett_method

    Interaction of triethylphosphine oxide with a Lewis acid Boron trihalides are archetypal Lewis acids and have AN values between 89 (BF 3 ) and 115 (BI 3 ). [ 2 ] The Gutmann–Beckett method has been applied to fluoroarylboranes [ 7 ] [ 8 ] such as B(C 6 F 5 ) 3 (AN 82), and borenium cations, and its application to these and various other boron ...
