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.

Answer 1

Answer:

B

Explanation:

Having the same electronegativity means that the both elements will form a nonpolar bond. The shared electrons of the bind will be found equidistant from the nucleus of the two atoms because none has an unusual ability to attract the electrons of a bond towards itself.
