positive inductive effect (+I) These groups can help stabilize positive charges in reactions such as protonation of bases • Bonding order and charge: As mentioned above it is important to consider both the electronegativity and bonding order when analyzing the inductive potential of an atom
The positive inductive effect becomes largest when methyl groups are directly bonded to the C bonded to the O in the hydroxyl group (identified as C1 as from now) The greater room that electrons have for moving reduces the repulsion forces also leading to a more stable structure
Inductive Effect The polarization of a ? bond due to electron withdrawing or electron donating effect of adjacent groups or atoms is called inductive effect In covalent compounds unlike atoms never share electron pair equally in forming sigma bond The e flow is slightly towards more electronegative atom
undoubtedly an inductive effect; the more electron-releasing ethyl group renders Et 2O and EtOH more basic than Me 2O and MeOH respectively in both phases d H 2O is the strongest base in water of this series on the basis of the excellent ability of its conjugate acid (H 3O +) to be solvated by water via hydrogen bonding It is the weakest

that the electronic effect (inductive plus mesomeric effect) of a substituent can be represented as the difference between the pKa value of its benzoic acid derivative and the pKa value of benzoic acid itself Various substituent effects can be concluded by looking at ? values displayed in Table 1 With ? =
What is the inductive effect?
(Main Article: Inductive Effect) The introduction of an electron-rich or electron-deficient species to a carbon chain results in the formation of a permanent dipole. This effect is called the inductive effect (since the dipole is induced by the difference in the electronegativities of the atoms in the molecule).
Why is the substituent effect positive in Halo groups?
The second kind of substituents is the halo- groups, for which the substituent effect is modestly positive. This can be attributed to the fact that even though the inductive effect is still negative, the resonance effect is positive (+R), canceling the former partially.
Why is the modified substituent constant ?p- negative?
Since the substituent is developing a negative charge during this process, the modified substituent constant will be labeled as ?p?. Similarly, if the electron-donating arising from mesomeric effects is extended to the reaction site via ‘through conjugation, the conjugated acid will less stable.
