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. WebThe effect on electron density in one portion of a molecule due to electron-withdrawing or electron-donating groups elsewhere in ... positive (inductive donation) and negative (inductive withdrawal) What is an example of a molecule which acts as a -I substituent?

Web13 dec. 2016 · The groups or atoms having electron withdrawing properties cause the negative inductive effect. Some examples are listed below according to the decreasing order of the –I 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
