C6H5CH2CH2
C6H5CH2CH2 is the condensed representation of the phenethyl group, also called the 2-phenylethyl substituent. It consists of a phenyl ring (C6H5) attached to a two-carbon chain (CH2–CH2–), with the attachment point at the terminal carbon. In shorthand, it is often written as Ph-CH2-CH2- and appears as a substituent in many organic compounds.
Nomenclature and relationships: The systematic name for this substituent is 2-phenylethyl. It is distinct from the
Reactivity and applications: The benzylic carbon (the CH2 directly attached to the aromatic ring) possesses relatively
Properties and context: As a structural fragment, the phenethyl group influences the physical properties of a
