  2. 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.

  3. 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 ...

  4. Baker–Nathan effect - Wikipedia

    en.wikipedia.org/wiki/Baker–Nathan_effect

    In organic chemistry, the Baker–Nathan effect is observed with reaction rates for certain chemical reactions with certain substrates where the order in reactivity cannot be explained solely by an inductive effect of substituents. [1] This effect was described in 1935 by John W. Baker and W. S. Nathan.

  5. Taft equation - Wikipedia

    en.wikipedia.org/wiki/Taft_equation

    where ⁡ is the ratio of the rate of the substituted reaction compared to the reference reaction, ρ* is the sensitivity factor for the reaction to polar effects, σ* is the polar substituent constant that describes the field and inductive effects of the substituent, δ is the sensitivity factor for the reaction to steric effects, and E s is ...

  6. Electrophilic aromatic directing groups - Wikipedia

    en.wikipedia.org/wiki/Electrophilic_aromatic...

    In general, the resonance effect of elements in the third period and beyond is relatively weak. This is mainly because of the relatively poor orbital overlap of the substituent's 3p (or higher) orbital with the 2p orbital of the carbon. Due to a stronger resonance effect and inductive effect than the heavier halogens, fluorine is anomalous.

  7. Induction - Wikipedia

    en.wikipedia.org/wiki/Induction

    Induction or inductive may refer to: Biology and medicine ... Inductive cleavage, in organic chemistry; Inductive effect, change in electron density;

  8. Fragmentation (mass spectrometry) - Wikipedia

    en.wikipedia.org/wiki/Fragmentation_(mass...

    The driving force of charge site-initiated fragmentation is the inductive effect of the charge site in radical cations. The electrons from the bond adjacent to the charge-bearing atom migrate to that atom, neutralizing the original charge and causing it to move to a different site.

  9. Electrostatic induction - Wikipedia

    en.wikipedia.org/wiki/Electrostatic_induction

    This effect is microscopic, but since there are so many molecules, it adds up to enough force to move a light object like Styrofoam. This change in the distribution of charge in a molecule due to an external electric field is called dielectric polarization , [ 8 ] and the polarized molecules are called dipoles .
