Reactions of Benzene

Reactions of Benzene

Reactions of Benzene: Benzene (C₆H₆) is a highly stable aromatic hydrocarbon due to its conjugated π-electron system. This stability makes benzene a prime candidate for electrophilic substitution reactions, where an electrophile replaces one of the hydrogen atoms on the benzene ring. Here are the key electrophilic substitution reactions of benzene: nitration, sulphonation, halogenation, Friedel-Crafts alkylation, … Read more

Hückel’s Rule

Hückel’s Rule

Hückel’s rule is a criterion used to determine if a molecule is aromatic. Aromatic compounds exhibit unusual stability and unique properties due to the delocalization of π electrons in a conjugated ring system. Here are the key points: Cyclic Structure: The molecule must have a ring structure. Planarity: The molecule must be planar, which allows … Read more

Aromatic Character in Benzene

Aromatic Character in Benzene

Explore the Aromatic Character in Benzene — aromatic compounds are a special class of cyclic compounds with exceptional stability due to the delocalized π electron cloud. Benzene is the prototypical aromatic compound, and its aromatic character can be understood through several criteria: Planarity: Benzene is a planar molecule, allowing optimal overlap of p orbitals. Cyclic … Read more

Large Intestine

The large intestine absorbs water and electrolytes from food, forming solid waste (feces) which is then excreted from the body. Anatomy The large intestine, or colon, is about 5 feet in length and is divided into several parts: the cecum, ascending colon, transverse colon, descending colon, sigmoid colon, rectum, and anus. 1. Cecum: A pouch-like … Read more

Resonance in Benzene

Resonance in Benzene

Benzene exhibits resonance, a phenomenon where the actual electronic structure is a hybrid of two or more contributing structures.  There are two main resonance structures: In one structure, double bonds are between C1-C2, C3-C4, and C5-C6. In the other structure, double bonds are between C2-C3, C4-C5, and C6-C1. These resonance structures imply that the π … Read more
