WebTherefore ortho or para addition will be much faster than meta addition. Thus electron donors (cation stabilizers) function as ortho/para directors. If a substituent is an electron withdrawer (cation destabilizer), it will be very harmful if the electrophile adds ortho or para relative to the substituent. Therefore ortho or para addition WebWhen an alkene reacts with an electrophile, as in the addition of HBr (Section 8.2 ), electrons from the alkene $\pi$ bond react with the electrophile, leading to a carbocation intermediate. ... Para substitution usually predominates over ortho due to steric effects. For example, acetanilide undergoes nitration primarily at the para position ...
