1.	Which of the following is correct regarding the reaction of alkali metals with halogens ?A. Alkali metals react vigorously with halogens to form ionic halides `M^(+)X^(-)`,B. The reactivity of alkali metals towards a particular halogen increases as we move down the group from Li to Cs.C. The reactivity of halogens towards a particular alkali metal decreases from `F_(2) "to" I_(2)`D. All of these.
Answer» Correct Answer - D `2M(s)+X_(2)to2M^(+)X^(-)` Reactivity of alkali metals increases down the group because of decrease of ionization enthalpy.
