fenüülrühmaga

Fenüülrühmaga refers to a chemical compound that contains a phenyl group. A phenyl group, denoted as C6H5-, is an organic substituent derived from benzene. It consists of a ring of six carbon atoms with alternating double bonds, with one hydrogen atom removed from the ring. This structure gives the phenyl group its characteristic aromaticity and reactivity.

Compounds containing a phenyl group are known as aromatic compounds. The presence of the phenyl ring significantly influences the physical and chemical properties of a molecule. It can increase lipophilicity, affect boiling and melting points, and participate in various chemical reactions, particularly electrophilic aromatic substitution. Many important organic molecules, including pharmaceuticals, dyes, and polymers, incorporate phenyl groups. For example, toluene is methylbenzene, where a methyl group is attached to a phenyl ring. Phenol is a hydroxyl group attached to a phenyl ring. The phenyl group itself is not typically found in isolation but is always bonded to another atom or functional group within a larger molecule. Its presence is a key identifier for a vast class of organic chemicals.
