Consider the following statements , `(I)` Amongst `HCl,HBr,HI` and `HOCl,HCl` is most stable to heat. `(II)` Chlorine gas if evolved when potassium chloride reacts with iodine. `(III)` The basicity of `F^(-),Cl^(-),Br^(-)` , and `I^(-)` follows the order `F^(-)gt Cl^(-) gtBr^(-) gtI^(-)` `(IV)` Sodium hypochlorite is used as bleaching and sterilising agent of these,A. `(I),(II),` and `(III)` are correctB. `(I),(II)`, and `(IV)` are correctC. `(I),(III)`, and `(IV)` are correctD. All of these |

Answer» Correct Answer - 3 `(I)HCl` because of high bond enthalpy of it. `(II)2KCIO_(3)+I_(2)rarr 2KIO_(3)+Cl_(2)` `(III)` Correct order , `F^(-)` because of high electron density on account of small size easily donate the electron pair, is strongest base. `(IV)` It is used as bleaching as well sterilising agent ( as it acts strong oxidising agent ). |
