Vedclass · Answer

(A) The halogens follow a trend in physical states: $F_2$ and $Cl_2$ are gases,$Br_2$ is a liquid,and $I_2$ is a solid at room temperature. Therefore,the statement that iodine is a solid is correct.Chlorine is soluble in water (forming chlorine water).Reactivity decreases down the group $(F_2 > Cl_2 > Br_2 > I_2)$,so chlorine is more reactive than bromine,and bromine is more reactive than iodine.
