Interpretation:
The relation of length of covalent bond with their strength is to be explained.
Concept introduction:
Bond strength means how strongly each atom is joined to one another atom and so, how amount of energy is required to dissociate the bond between the two atoms. Covalent bond is that bond which involves the sharing of electron pairs between atoms. If bond length is shorter then covalent bond is strongest.
Answer to Problem 92A
Covalent bond is that bond which involves the sharing of electron pairs between the atoms. If bond length is shorter then covalent bond is strongest. If bond length is shorter then covalent bond is strongest. The strength of a bond between two atoms increases as the number of electrons pairs in the bond increases.
Explanation of Solution
Bond strength means how strongly each atom is joined to one another atom and so, how amount of energy is requires dissociating the bond between the two atoms. The bond length is defined as the average distance between the nuclei of two bonded atoms in a molecule. covalent bond is that bond which involves the sharing of electron pairs between atoms. If bond length is shorter then covalent bond is strongest. The strength of a bond between two atoms increases as the number of electrons pairs in the bond increases. Normally when the bond strength is increases , the bond length is decreases. On the basis of this concept, conclusion is that the triple bonds are stronger and shorter than double bonds between the same two atoms.
Covalent bond is that bond which involves the sharing of electron pairs between the atoms. If bond length is shorter then covalent bond is strongest. If bond length is shorter then covalent bond is strongest. The strength of a bond between two atoms increases as the number of electrons pairs in the bond increases.
