Acid strength increases in the order of _____________(a) HF ≪ HCl ≪ HBr ≪ HI(b) HF ≪ HBr ≪ HCl ≪ HI(c) HI ≪ HCl ≪ HBr ≪ HF(d) HCl ≪ HF ≪ HBr ≪ HIThis question was posed to me during an interview.I'd like to ask this question from Equilibrium topic in section Equilibrium of Chemistry – Class 11

Answer»

Correct answer is (a) HF ≪ HCl ≪ HBr ≪ HI

The BEST explanation: The correct order of INCREASE in ACIDIC STRENGTH is HF ≪ HCl ≪ HBr ≪ HI. There are many FACTORS affecting acid strength. Hear the hydrogen-acid Bond strength decreases, as the acid strength increases.
