The correct Answer is:
To determine which compound forms a `KHX2` type compound, we need to analyze the behavior of hydrogen halides. The options likely include hydrogen fluoride (HF), hydrogen chloride (HCl), hydrogen bromide (HBr), and hydrogen iodide (HI). ### Step-by-Step Solution: 1. **Understand the Halogen Group**: - The halogens include fluorine (F), chlorine (Cl), bromine (Br), and iodine (I). Each of these can form hydrogen halides (HF, HCl, HBr, HI). 2. **Electronegativity Consideration**: - Electronegativity is the tendency of an atom to attract electrons. The order of electronegativity for the halogens is: - F > Cl > Br > I. - Fluorine has the highest electronegativity, which affects its chemical behavior. 3. **Behavior of Hydrogen Halides**: - When hydrogen halides are considered, they can sometimes form complex compounds with potassium (K). - HF is unique among hydrogen halides because it can form a complex compound with potassium fluoride (KF). 4. **Formation of KHX2 Type Compound**: - The `KHX2` type compound refers to a compound where K is bonded to two halogen atoms (HX). - HF can react with KF to form KHF2. This reaction involves the association of HF molecules and is unique to HF. 5. **Conclusion**: - Among the hydrogen halides, only HF forms a `KHX2` type compound (KHF2) when reacted with KF. Other halides like HCl, HBr, and HI do not exhibit this behavior. ### Final Answer: - The compound that forms `KHX2` type compound is **HF (Hydrogen Fluoride)**.
