halogencarbonatom
Halogencarbonatom refers to a carbon atom bonded covalently to a halogen — fluorine, chlorine, bromine, or iodine. This motif occurs in a wide range of organic compounds, collectively known as haloalkanes and halomethanes. The carbon–halogen bond is typically polar, with electron density pulled toward the halogen. This polarity influences reactivity and physical properties such as boiling points.
Bond strength and reactivity follow a general trend: C–F bonds are the strongest and least reactive toward
In synthesis, halogencarbonatoms are common sites for carbon–halogen bond cleavage. Nucleophilic substitution (SN1 or SN2) replaces
Common classes include haloalkanes (R–X) and haloaromatics (Ar–X). Examples include chloromethane (CH3Cl), bromoethane (C2H5Br), and fluoromethane
