NEET2024Chemistryp Block Elements (Group 15, 16, 17 & 18)Actual
Identify the incorrect statement from the following:
Options
- AThe acidic strength of HX (X= F , Cl , Br and I ) follows the order: HF HCl HBr HI .
- BFluorine exhibits -1 oxidation state whereas other halogens exhibit +1,+3,+5 and +7 oxidation states also.
- CThe enthalpy of dissociation of F ₂ is smaller than that of Cl ₂ .
- DFluorine is stronger oxidising agent than chlorine.
Correct answer
A. The acidic strength of HX (X= F , Cl , Br and I ) follows the order: HF HCl HBr HI .
Step-by-step solution
The acidic strength of HX follows the order HF HCl HBr HI This is because bond enthalpy of hydrides of group 17 decreases down the group.
