Final answer:
The bonds can be arranged in order of increasing ionic character as K&O < C&H < Cl&F < N&N < Li&F.
Step-by-step explanation:
The ionic character of a bond is determined by the electronegativity difference between the atoms involved. The greater the electronegativity difference, the more ionic the bond becomes. In this case, we are given the bonds K&O, Li&F, C&H, N&N, and Cl&F.
- K&O: Potassium (K) and Oxygen (O) are both nonmetals. As a general rule, bonds between two nonmetals are covalent and have low ionic character.
- Li&F: Lithium (Li) is a metal and Fluorine (F) is a nonmetal. Bonds between a metal and a nonmetal are often ionic, so this bond has moderate ionic character.
- C&H: Carbon (C) and Hydrogen (H) are both nonmetals, so this bond is covalent and has low ionic character.
- N&N: Nitrogen (N) is a nonmetal and forms covalent bonds with other nonmetals.
- Cl&F: Chlorine (Cl) is a nonmetal and Fluorine (F) is also a nonmetal. So this bond is covalent with low ionic character.
Therefore, the bonds can be arranged in order of increasing ionic character as follows:
K&O < C&H < Cl&F < N&N < Li&F
