Bond dissociation energy of 500 KJ mol -1 may be assigned to
Bond dissociation energy of 500 KJ mol-1 may be assigned to
- A) ionic bonding
- B) covalent bonding
- C) hydrogen bonding
- D) metallic bonding
Correct Answer: A) ionic bonding
Explanation
This question is asking which type of bonding can be assigned a bond dissociation energy of 500 KJ mol-1.Bond dissociation energy refers to the amount of energy required to break a bond between two atoms. The higher the bond dissociation energy, the stronger the bond.
The options given are ionic bonding, covalent bonding, hydrogen bonding, metallic bonding, and van-der-waals bonding.
The correct answer is Option A, which is ionic bonding. Ionic bonding involves the transfer of electrons from one atom to another, resulting in positively-charged cations and negatively-charged anions that are held together by electrostatic attractions. These attractions are very strong, hence the high bond dissociation energy of 500 KJ mol-1 can be assigned to ionic bonding.
Covalent bonding involves the sharing of electrons between atoms, while hydrogen bonding involves a special type of dipole-dipole interaction between molecules containing hydrogen and electronegative elements. Metallic bonding involves the sharing of electrons between metal atoms, while van-der-waals bonding involves weak intermolecular forces between nonpolar molecules.
