To determine the correct order of covalent character, we need to compare the electronegativity difference between the atoms in each compound. The greater the electronegativity difference, the more ionic the bond becomes.

Hg2Cl2: Mercury (Hg) is a transition metal with low electronegativity, and chlorine (Cl) is a highly electronegative nonmetal. The electronegativity difference is relatively small, suggesting a higher covalent character.

HgCl2: Again, mercury (Hg) is a transition metal with low electronegativity, and chlorine (Cl) is highly electronegative. The electronegativity difference is similar to Hg2Cl2, indicating a higher covalent character.

LiF: Lithium (Li) is a metal with low electronegativity, and fluorine (F) is a highly electronegative nonmetal. The electronegativity difference is large, indicating a more ionic character.

LiCl: Lithium (Li) is a metal with low electronegativity, and chlorine (Cl) is a highly electronegative nonmetal. The electronegativity difference is similar to LiF, suggesting a more ionic character.

SF4: Sulfur (S) is a nonmetal with moderate electronegativity, and fluorine (F) is a highly electronegative nonmetal. The electronegativity difference is relatively small, indicating a higher covalent character.

SF6: Sulfur (S) is a nonmetal with moderate electronegativity, and fluorine (F) is a highly electronegative nonmetal. The electronegativity difference is similar to SF4, suggesting a higher covalent character.

PbCl2: Lead (Pb) is a metal with low electronegativity, and chlorine (Cl) is a highly electronegative nonmetal. The electronegativity difference is relatively small, indicating a higher covalent character.

PbCl4: Lead (Pb) is a metal with low electronegativity, and chlorine (Cl) is a highly electronegative nonmetal. The electronegativity difference is similar to PbCl2, suggesting a higher covalent character.

Based on the analysis above, the correct order of increasing covalent character is: LiF > LiCl > PbCl2 > PbCl4 > Hg2Cl2 > HgCl2 > SF4 < SF6
