question 3 of 22
figure a and figure b represent examples of different types of chemical bonding. identify the descriptions and properties that best represent each figure. all of the descriptions and properties may not be used.
figure a
figure b
nonpolar covalent
polar covalent
equal sharing of electrons
unequal sharing of electrons
answer bank
transfer of electrons
n-h bond
ionic
na-cl bond
cl-cl bond

Explanation:

• Figure A: It represents non - polar covalent bonding. In non - polar covalent bonding, there is an equal sharing of electrons. The \(Cl - Cl\) bond is a non - polar covalent bond because the two chlorine atoms have the same electronegativity, so they share the electrons equally.
• Figure B: It represents polar covalent bonding. In polar covalent bonding, there is an unequal sharing of electrons. The \(N - H\) bond is a polar covalent bond. Nitrogen is more electronegative than hydrogen, so it pulls the shared electrons closer to itself, creating a dipole moment (as indicated by the arrow in Figure B).

Answer:

• Figure A: non - polar covalent, equal sharing of electrons, \(Cl - Cl\) bond
• Figure B: polar covalent, unequal sharing of electrons, \(N - H\) bond
