Which one of the following generally gets displaced by more electro positive metals in nonmetal displacement reactions.

Options

A. a `H_(2)`
B. b `N_(2)`
C. c `F_(2)`
D. d `Cl_(2)`

Answer

To solve the question "Which one of the following generally gets displaced by more electropositive metals in non-metal displacement reactions?", we can follow these steps:

### Step 1: Understand the Concept of Displacement Reactions
Displacement reactions occur when a more reactive element displaces a less reactive element from a compound. In the context of non-metal displacement reactions, we are particularly interested in how metals interact with non-metals.

**Hint:** Recall that reactivity series helps us determine which elements can displace others in reactions.

### Step 2: Identify the Role of Electropositivity
Electropositivity refers to the tendency of an element to lose electrons and form positive ions. More electropositive metals are more reactive and can displace less electropositive elements from their compounds.

**Hint:** Remember that metals are generally electropositive, and their reactivity increases down the group in the periodic table.

### Step 3: Analyze the Example Provided
The video transcript mentions an example involving zinc (Zn) and hydrogen (H). The reaction is:
\[ \text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2 \]
In this reaction, zinc, being more electropositive than hydrogen, displaces hydrogen from hydrochloric acid.

**Hint:** Look for examples in the periodic table where metals displace hydrogen or other non-metals.

### Step 4: Conclude Based on the Electrochemical Series
From the electrochemical series, we can see that hydrogen is positioned below the more electropositive metals. This indicates that hydrogen can be easily displaced by these metals.

**Hint:** Use the electrochemical series to compare the positions of elements and determine their reactivity.

### Step 5: Final Answer
Based on the analysis, we conclude that hydrogen is the correct answer, as it is generally displaced by more electropositive metals in non-metal displacement reactions.

**Final Answer:** Hydrogen is the element that generally gets displaced by more electropositive metals in non-metal displacement reactions.
