Chapter 12.1, Problem 4RQ

Interpretation Introduction

Interpretation:

The given compounds are to match with the figures given.

Concept introduction:

Chemical bond is of three types:

• Ionic bond
• Chemical bond
• Coordinate bond

Ionic bonds are formed when there is complete transfer of electrons from one atom to another forming the bonds.

Covalent bond is formed by sharing of electrons between the atoms forming the bonds

Polar covalent bond is formed between two different atoms.

Non-polar covalent bond is between two same atoms.

Answer to Problem 4RQ

Figure (a) is of$O_2$

Figure (b) is of$HF$

Figure (c) is of$NaCl$

Explanation of Solution

Figure a shows sharing of electrons and distribution of electrons is same. So it shows non-polar covalent bond which is formed by oxygen molecule.

Figure b shows sharing of electron and polarities. So it shows polar covalent bond which is formed by $HF$ .

Figure c shows ions that means ionic bond which exists in $NaCl$

Conclusion

Thus, figures can help to know what type of bond is formed between two atoms.
