To determine the electronegativity for each bond you need to calculate the difference of electronegativity of the atoms forming the bond.

If the difference is equal or greater than 1.7 you have an ionic bond.

If the difference is between 0.4 and 1.6 you have a polar covalent bond.

If the difference is between 0 and less than 0.4 you have a nonpolar covalent bond.

1) In NH₃ there is a nitrogen - hydrogen bond.

electronegativity of nitrogen - electronegativity of hydrogen =

3 - 2.2 = 0.8 → polar covalent bond

2) In N₂ there is a nitrogen-nitrogen bond.

electronegativity of nitrogen - electronegativity of nitrogen =

3 - 3 = 0 → nonpolar covalent bond

3) In H₂O there is an oxygen - hydrogen bond.

electronegativity of oxygen - electronegativity of hydrogen =

3.5 - 2.2 = 1.3 → polar covalent bond

4) In PCl₃ there is a chlorine - phosphorus bond.

electronegativity of chlorine - electronegativity of phosphorus = 3 - 2.1 = 0.9 → polar covalent bond

4) In HBr there is a bromine - hydrogen bond.

electronegativity of bromine - electronegativity of hydrogen = 2.8 - 2.2 = 0.6 → polar covalent bond

5) In MgCl₂ there is a chlorine - magnesium bond.

electronegativity of chlorine - electronegativity of magnesium = 3 - 1.2 = 1.8 → ionic bond

6) In F₂ there is a fluorine - fluorine bond.

electronegativity of fluorine - electronegativity of fluorine =

4 - 4 = 0 → nonpolar covalent bond

7) In CO₂ there is an oxygen - carbon bond.

electronegativity of oxygen- electronegativity of carbon =

3.5 - 2.5 = 1 → polar covalent bond

8) In LiCl there is a chlorine - lithium bond.

electronegativity of chlorine - electronegativity of lithium =

3 - 1 = 2 → ionic bond

9) In Na₂O there is an oxygen - sodium bond.

electronegativity of oxygen - electronegativity of sodium =

3.5 - 0.9 = 2.6 → ionic bond

10) In CCl₄ there is a chlorine - carbon bond.

electronegativity of chlorine - electronegativity of carbon =

3 - 2.5 = 0.5 → polar covalent bond

Select the correct answer. Based on the reactivities of the elements involved, which reaction will form products that are more s

FinnZ [79.3K]

Answer: The correct answer is option B.

Explanation: Reactivity of elements is defined as the tendency to loose or gain electrons.

These reactions are a type of single displacement reactions. A single displacement reaction is a type of reaction in which an element displaces another element in a chemical reaction. These are studied with the help of reactivity series.

The element which lies above in the reactivity series can easily displace the element which lies below in the reactivity series.

Option A: This reaction will not yield a stable product because Zinc lies below Aluminium in the reactivity series.

$AlBr_3+Zn\rightarrow \text{No reaction}$

Option B: This reaction will yield a stable product because Sodium lies above Calcium in the reactivity series.

$CaBr_2+2Na\rightarrow 2NaBr+Ca$

Option C: This reaction will not yield a stable product because Hydrogen lies below Magnesium in the reactivity series.

$MgBr_2+H_2\rightarrow \text{No reaction}$

Option D: This reaction will not yield a stable product because Calcium lies below Barium in the reactivity series.

$BaBr_2+Ca\rightarrow \text{No reaction}$

Option E: This reaction will not yield a stable product because barium lies below Lithium in the reactivity series.

$2LiBr+Ba\rightarrow \text{No reaction}$
