Question

question 4. which of the following elements are less electronegative than carbon? select all that apply.

oxygen (o)

germanium (ge)

chlorine (cl)

magnesium (mg)

nitrogen (n)

Explanation:

To determine which elements are less electronegative than carbon (C, electronegativity ~2.55), we use electronegativity trends:

• Oxygen (O): Electronegativity ~3.44 (higher than C).
• Germanium (Ge): Electronegativity ~2.01 (lower than C, as Ge is below C in Group 14, and electronegativity decreases down a group).
• Chlorine (Cl): Electronegativity ~3.16 (higher than C).
• Magnesium (Mg): Electronegativity ~1.31 (lower than C, as Mg is a metal in Group 2, and metals have lower electronegativity than non - metals like C).
• Nitrogen (N): Electronegativity ~3.04 (higher than C).

So Germanium (Ge) and Magnesium (Mg) have lower electronegativity than carbon.

Answer:

B. Germanium (Ge), D. Magnesium (Mg)
