Question

bonding of atoms in reactions quick check 4 of 5 which statement best explains the difference between polar and nonpolar covalent bonds? (1 point) polar covalent bonds give/take electrons, while nonpolar covalent bonds share electrons. polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally. polar covalent bonds share electrons equally, while nonpolar covalent bonds share electrons unequally. polar covalent bonds share electrons, while nonpolar covalent bonds give/take electrons.

Explanation:

Covalent bonds involve sharing electrons. In polar covalent bonds, due to differences in electronegativity between atoms, electrons are shared unequally. In nonpolar covalent bonds, atoms have similar electronegativities, so electrons are shared equally. Options A and D are incorrect as covalent bonds (both polar and non - polar) involve sharing electrons, not giving/taking (which is characteristic of ionic bonds). Option C has the definitions reversed.

Answer:

B. Polar covalent bonds share electrons unequally, while nonpolar covalent bonds share electrons equally.
