Problems with Electrophilic Aromatic Substitution Reactions

🔑Electrophilic aromatic substitution reactions involve replacing hydrogen atoms with an alkyl group or other substituents on a benzene ring.

🕐Steric hindrance can affect the regioselectivity of electrophilic aromatic substitution reactions, leading to different major products.

📌Frito-crafts alkylation involves replacing a hydrogen atom on a benzene ring with an alkyl group using a lewis acid catalyst.

🔬Nitration of benzene replaces a hydrogen atom with a nitro group (NO2) using concentrated sulfuric acid as a catalyst.

🔍Understanding directing and steric effects is crucial in predicting the major products of electrophilic aromatic substitution reactions.
