If the atom bonded to the ring has one or more non-bonding valence shell electron pairs, as do nitrogen, oxygen and the halogens, electrons may flow into the aromatic ring by p-π conjugation ( resonance ), as …

WebThe inductive effect is divided into two types based on the electron withdrawing or electron releasing nature of atom/group inducing it. The strength of inductive effect is measured by comparing with that of hydrogen. 1) Negative inductive effect (-I): The electron withdrawing nature of groups or atoms is called as negative inductive effect.

If we were to draw the resonance structures showing delocalisation of the lone pair into the carbonyl group, we necessarily would have to show the C-O $\pi$ bond … Electron donating groups are typically divided into three levels of activating ability (The "extreme" category can be seen as "strong".) Electron withdrawing groups are assigned to similar groupings. Activating substituents favour electrophilic substitution about the ortho and para positions. Weakly deactivating groups direct electrophiles to attack the benzene molecule at the ortho- and para- positions, … small narrow side table with a drawer

Substituents with several bonds to electronegative atoms (e.g.-CF 3) adjacent to the pi system are electron withdrawing groups (EWG) - they deactivate the aromatic ring by decreasing the electron density on the ring through a inductive withdrawing effect.The net overall effect is similar to that described above for other electron withdrawing groups.

WebThe effect of meta-methoxy substitution is primarily inductive withdrawal of electrons, and is distance dependent—thus larger for compounds with fewer σ bonds between the substituent and the acidic X–H bond (Figure 1.5).
