Question

Which is the weakest type of bonding in solids?
A. Ionic
B. Covalent
C. Metallic
D. Van der Waal’s

Answer 1

Hint:Recall the concept of bond between the two atoms or molecules. Recall the basics of the different types of the bonds formed between the atoms in the solids. Check which of these bonds found in solids are strong and weak. Hence, determine the weakest type of bond formed in the solids from the given options.

Complete answer:
The ionic bond is the strongest type of bond in solids. The covalent bond is weaker than ionic bond and metallic bonds are weaker than covalent bond.Hence, the options A, B and C are incorrect.The weakest type of bond in the solids is Van der Waals bond.

Hence, the correct option is D.

Additional information:
There are different types of bonds such as ionic bond, covalent bond, metallic bond, Van der Waals bond, etc.The ionic bond is formed between two ions out of which one is positive ion and one is negative ion. The ionic bonds are mostly found in the salts as they are mainly formed from the ions.

The covalent bond is formed by the sharing of electrons between the two atoms. In this covalent bond, the same electrons are shared by the two atoms to form a bond.The metallic bond is formed by the electrostatic force of attraction between the electrons and positive metal ions.The Van der Waals bond is formed by the attraction or repulsion between the atoms, molecules or ions.

Note:The students should not get confused between different bonds in the solids to determine which of the bonds is strongest and which one is weakest. If one could not compare these different bonds correctly then he/she will not be able to determine which bond among the given options is the weakest.
