Question

question 3 of 10
what kind of covalent bond involves an even sharing of electrons?
a. a dipole-dipole bond
b. a nonpolar covalent bond
c. a polar covalent bond
d. a metallic bond

Explanation:

To solve this, we analyze each option:

• Option A: Dipole - dipole bonds are intermolecular forces, not covalent bonds, so A is incorrect.
• Option B: In a nonpolar covalent bond, electrons are shared equally (evenly) between atoms because the atoms have similar electronegativities.
• Option C: In a polar covalent bond, electrons are shared unequally due to a difference in electronegativities, so C is incorrect.
• Option D: Metallic bonds are found in metals and involve a sea of delocalized electrons, not the sharing of electrons in the way covalent bonds do, so D is incorrect.

Answer:

B. A nonpolar covalent bond
