Explanation Electrophilic substitution reactions in naphthalene: Fries rule: The most stable arrangement of a polynuclear compound is that form which has a maximum number of rings in the benzenoid condition. The most efficient stabilization of the intermediate carbocation produced by electrophilic attack on naphthalene comes from those resonance forms that retains one fully benzenoid ring. In case of 1-substitution, two structures can be obtained(A, B). In case of 2-substitution, one structure can be obtained(F). The intermediate from attack at the 1-position is more stable and therefore, the 1-substituted product is more favored in the electrophilic substitution of naphthalene. The carbocation formed by the attack of electrophile at 1-position of naphthalene is much more stabilize by resonance since it has four contributing structures in which aromatic character is retained in one of the ring...

Introduction to Organic Chemistry

The field of chemistry which deals with the studies of reactions, structures, and properties of organic compounds that comprise carbon bonded through covalent bonding is organic chemistry. The studies regarding the structure of organic compounds could be…

Vinyl Group

Vinyl group is the name given to the functional group of -CH=CH2. It can be seen as an ethene molecule with one less hydrogen in number. Hence it is also called as ethenyl group at times.

Straight Chain Hydrocarbons

The requirement to identify each compound needs a richer number of words than informative prefixes like n and iso. The identification of organic molecules is made easier by the use of systematic nomenclature schemes. The organic chemistry nomenclature ha…

Conjugated Compounds in Organic Chemistry

The delocalization of electrons in a molecule is called conjugation in organic chemistry. This delocalisation process of electrons leads to the shortenings or elongations of chemical bonds, but at the same time it causes changes in the chemical propertie…

Alpha Carbon And Alpha Protons

The carbon directly attached to the functional group in an organic molecule is referred to as the alpha carbon and the hydrogen attached to an alpha carbon are termed as the alpha hydrogens or alpha protons. These alpha carbon atoms and alpha hydrogen at…
