“1-bromopropane is heated with NaOH(aq) and separately with NaOH in ethanol. State the major product in each case and explain.” Before looking at the answers, you must identify
bond is the most polar, it is also the . Reaction rate is determined by bond enthalpy , not polarity. C-I has the lowest bond enthalpy (weakest bond). C-F has the highest bond enthalpy (strongest bond). The Product: Alcohol + Hydrogen halide
Halogenoalkanes (haloalkanes) are alkane derivatives in which one or more hydrogen atoms have been replaced by halogen atoms (fluorine, chlorine, bromine, iodine). Their chemical behaviour is dominated by the polar carbon–halogen (C–X) bond: the carbon bears a partial positive charge (δ+) and the halogen a partial negative charge (δ–). That polarization makes haloalkanes susceptible to nucleophilic substitution and elimination reactions, and also to radical processes under appropriate conditions. This essay summarizes the major reaction types, mechanisms, factors that influence reactivity, typical reagents and conditions, and important examples with practical relevance.
