Vedclass · Answer

(B) The reactivity of alkali metals towards water increases down the group. $Li$ is the least reactive,while $Cs$ is the most reactive. This is because the reactivity depends on the ease of losing an electron,which is determined by the ionization enthalpy. As we move down the group,the ionization enthalpy decreases,making the metal more electropositive and thus more reactive. Therefore,$Na$ is more electropositive than $Li$,leading to a more vigorous reaction with water.
