Answer

Explanation:

Step1: Find electronegativity of C

The electronegativity of carbon (C) is 2.5.

Step2: Calculate difference for C - C

For two carbon - carbon atoms, the electronegativity difference $\Delta\chi=|2.5 - 2.5|=0$. Since $0<1.5$, it is covalent.

Step3: Find electronegativities of Mg and Cl

The electronegativity of magnesium (Mg) is 1.2 and of chlorine (Cl) is 3.0.

Step4: Calculate difference for Mg - Cl

The electronegativity difference $\Delta\chi=|3.0 - 1.2| = 1.8$. Since $1.8>1.5$, it is ionic.

Answer:

Electronegativity difference of C and C: 0, covalent Electronegativity difference of Mg and Cl: 1.8, ionic
