Step 1:I'll solve this problem step by step following the specified LaTeX formatting guidelines:
Step 2:: Understand Electronegativity Difference
Electronegativity difference is used to determine the polarity of a chemical bond by comparing the electronegativity values of two atoms in a bond.
Step 3:: Recall Polarity Criteria
- $$\Delta\chi > 1.7$$: Ionic bond
The general rules for bond polarity based on electronegativity difference are:
Step 4:: Analyze the Given Electronegativity Difference
The problem states an electronegativity difference of $$0.4$$.
Step 5:: Determine Bond Polarity
Since the electronegativity difference is exactly $$0.4$$, this falls at the boundary of the nonpolar covalent bond range.
Final Answer
Nonpolar (technically at the boundary between nonpolar and polar covalent bonds)
