Explain: In alkoxybenzene,the alkoxy group is ortho-para directing,but why does electrophilic substitution occur mainly at the para-position and to a lesser extent at the ortho-position?

(N/A) $(i)$ The alkoxy group decreases the electron density at the ortho-position due to its electron-withdrawing inductive effect $(-I)$.
$(ii)$ The steric hindrance of the alkoxy group makes it difficult for the electrophile to reach the ortho-position. Due to these two reasons,the electrophilic reagent attaches more to the para-position.
$(iii)$ In reactions like bromination,nitration,and Friedel-Crafts reactions,the para-product is the major product,and the ortho-substituted product is the minor product.
