Options

A. higher ionization potential
B. lower electron negativity
C. higher electronegativity
D. lower atomic redius

Answer

To determine the properties of the compound X-O-H and its ability to act as a base compared to hydrogen, we need to analyze the characteristics of the element X in relation to the oxygen and hydrogen atoms in the compound. Here’s a step-by-step breakdown of the solution:

### Step 1: Understanding the Compound
The compound X-O-H consists of an element X bonded to an oxygen atom, which in turn is bonded to a hydrogen atom. This structure suggests that X can influence the behavior of the hydroxyl group (OH).

**Hint:** Consider the role of the bonds in determining the compound's behavior.

### Step 2: Identifying Base Characteristics
For X-O-H to act as a strong base, it must be able to ionize effectively to produce hydroxide ions (OH⁻). This means that the bond between X and O (XO bond) must be weak enough to break easily, allowing the release of OH⁻ ions.

**Hint:** Think about what properties of X would make the XO bond weaker.

### Step 3: Analyzing Ionization Potential
If X has a higher ionization potential, it means that it holds onto its electrons tightly and is less likely to lose them. This would make the XO bond stronger, which is not favorable for base behavior.

**Hint:** Consider how ionization potential affects the ability of an atom to form positive ions.

### Step 4: Considering Electronegativity
Electronegativity is a measure of an atom's ability to attract electrons. If X has lower electronegativity than oxygen, the electrons in the XO bond will be more attracted to oxygen. This would make the XO bond weaker and more likely to break, facilitating the release of OH⁻ ions.

**Hint:** Compare the electronegativities of X and O to determine the bond strength.

### Step 5: Evaluating Atomic Radius
If X has a smaller atomic radius, it is likely to have higher electronegativity. A smaller atomic radius means that the electrons are held closer to the nucleus, making it less likely for the bond to break.

**Hint:** Think about how atomic size relates to electronegativity and bond strength.

### Step 6: Conclusion
Based on the analysis, for X-O-H to act as a strong base, X should have a lower electronegativity compared to oxygen. This allows the XO bond to be weaker, facilitating the release of hydroxide ions.

**Final Answer:** The compound X-O-H is likely to act as a base if compared to hydrogen, if X has **lower electronegativity**.
