  2. Bent's rule - Wikipedia

    en.wikipedia.org/wiki/Bent's_rule

    The inductive effect is the transmission of charge through covalent bonds and Bent's rule provides a mechanism for such results via differences in hybridisation. In the table below, [ 26 ] as the groups bonded to the central carbon become more electronegative, the central carbon becomes more electron-withdrawing as measured by the polar ...

  3. Inductive effect - Wikipedia

    en.wikipedia.org/wiki/Inductive_effect

    The effect of the sigma electron displacement towards the more electronegative atom by which one end becomes positively charged and the other end negatively charged is known as the inductive effect. The - I effect is a permanent effect & generally represented by an arrow on the bond.

  4. Electronegativity - Wikipedia

    en.wikipedia.org/wiki/Electronegativity

    Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons (or electron density) when forming a chemical bond. [1] An atom's electronegativity is affected by both its atomic number and the distance at which its valence electrons reside from the charged nucleus. The higher the ...

  5. Electronic effect - Wikipedia

    en.wikipedia.org/wiki/Electronic_effect

    Induction is the redistribution of electron density through a traditional sigma bonded structure according to the electronegativity of the atoms involved. The inductive effect drops across every sigma bond involved limiting its effect to only a few bonds.

  6. Sigma electron donor-acceptor - Wikipedia

    en.wikipedia.org/wiki/Sigma_electron_donor-acceptor

    The more negative sEDA, the more sigma-electron withdrawing is the substituent (see the table below). The sEDA parameter for a given substituent is calculated by means of quantum chemistry methods. The model molecule is the monosubstituted benzene.

  7. Markovnikov's rule - Wikipedia

    en.wikipedia.org/wiki/Markovnikov's_rule

    The rule states that with the addition of a protic acid HX or other polar reagent to an asymmetric alkene, the acid hydrogen (H) or electropositive part gets attached to the carbon with more hydrogen substituents, and the halide (X) group or electronegative part gets attached to the carbon with more alkyl substituents. This is in contrast to ...

  8. Field effect (chemistry) - Wikipedia

    en.wikipedia.org/wiki/Field_effect_(chemistry)

    Loss of a proton results in a negative charge which is less stable if there is already an inherent concentration of electrons. [17] This can be attributed to a field effect because in the same compound with the chlorines pointed away from the acidic group the pKa is lower, and if the effect were inductive the conformational position would not ...

  9. Mesomeric effect - Wikipedia

    en.wikipedia.org/wiki/Mesomeric_effect

    The mesomeric effect as a result of p-orbital overlap (resonance) has absolutely no effect on this inductive effect, as the inductive effect has purely to do with the electronegativity of the atoms and their topology in the molecule (which atoms are connected to which). Specifically the inductive effect is the tendency for the substituents to ...
