Nettet1. Basically there are two things that determine the reactivity of Halgenoalkanes, Polarity and Bond enthalpy. Polarity- the Carbon fluorine bond is the most polar, so can attract a nuclephile most easily, so you it would lead you to believe that it is the most reactive. Bond enthalpy- The carbon -Iodine bond is the easiest to brake, so thats ... NettetCalculation reaction energy for the propagation step of mono-chlorination of methane (referring to the corresponding bond energies in Table 9.1.) Solution: Step 1: H — CH 3 + •Cl → CH 3 • + H — Cl. The H — CH 3 bond broken, absorb energy, so +440 kJ. The H — Cl bond formed, release energy, so – 432 kJ. ΔH 1 = +440 + (-432) = +8 kJ

NettetA bond between two atoms or more atoms is non-polar if the atoms have the same electronegativity or a difference in electronegativities that is less than 0.4. An example of a non-polar bond is the bond in chlorine. Chlorine contains two chlorine atoms. NettetBoth increased number of C-H bonds and fewer C-Z bonds II > IV > I > III Rank the following compounds in order of decreasing reactivity in nucleophilic addition reactions, starting with the most reactive compound. bollywood temple menu
