Question

the elements c and se have the same electronegativity value, 2.55. which of the following claims about the compound that forms from c and se is most likely to be true? a the carbon - to - selenium bond is unstable. b the carbon - to - selenium bond is nonpolar covalent. c the compound has the empirical formula cse. d a molecule of the compound will have a partial negative charge on the carbon atom.

Explanation:

Step1: Recall bond - polarity rule

If two atoms have the same electronegativity value, the electrons in the bond between them are shared equally.

Step2: Analyze each option

• Option A: There is no information suggesting the bond is unstable just from electronegativity values.
• Option B: Since C and Se have the same electronegativity (2.55), the carbon - to - selenium bond is nonpolar covalent as electrons are shared equally.
• Option C: The empirical formula cannot be determined solely from electronegativity values.
• Option D: Since electronegativities are equal, there will be no partial negative charge on the carbon atom.

Answer:

B. The carbon - to - selenium bond is nonpolar covalent.
