Polar vs. Non-Polar

Polar vs. Non-polar Coordination is Key Covalent or Nah? Random Regents LETS BOND

Does this compound have polar or non-polar bonds?

Answer: Polar Bonds! Due to differences in electronegativity Lets Bond

Polar molecules, are easily soluble in what types of substances?

Lets Bond Answer: Polar Substances (such as H 2 O) Polar molecules are soluble in polar substances Non-polar molecules are soluble in non-polar substances

Which type of bond conducts electricity? a) Polar covalent bonds b) Non-polar covalent bonds c) Both polar and non-polar covalent bonds d) Neither type of bonds

Answer: (a): Polar covalent bonds *These molecules conduct electricity poor/medium making them weak electrolytes* Lets Bond

With respect to non-polar bonds, do polar covalent bonds have a higher or lower force of attraction between molecules?

Answer: They have a higher force of attraction Electronegativity Diff: 0< x<1.7 *Non-polar covalent bonds:* Electronegativity Diff: 0 Lets Bond

In coordinate covalent bonding, what element’s ion is most likely to “link on”

Answer: Hydrogen Ion Because it has no electrons Lets Bond

In coordinate covalent bonding, are electrons shared or donated. How many electrons are shared or donated?

Answer: At least one pair of electrons is donated to the ion joining the compound Lets Bond

In a network of solids, what type of bonding exists between atoms?

Answer Covalent Bonds! *Network solids are a giant network of covalently bonded atoms, they’re extremely strong structures, with a high melting point, and do not dissolve* Lets Bond

This equation represents what process/ bonding?

Answer: Coordinate covalent bonding Lets Bond

Bonds between a metal and a non- metal… Covalent or nah?

Answer: Nah, Bonding between a metal and a non-metal is ionic bonding Lets Bond

Bonds between nonmetals Covalent or nah?

Answer: Covalent! Lets Bond

Bonds that are formed due to the electrical attraction between positive and negative ions Covalent or nah?

Answer: Nah These types of bonds are ionic bonds, where there is a transfer of electrons Lets Bond

Bonds that are formed when two atoms share one or more pairs of electrons Covalent or nah?

Answer Covalent! Two non-metals share one or more pairs of electrons Lets Bond

Bonds that are formed when there’s a transfer of electron from one atom to another Covalent or nah?

Answer Nah *This type of bond, where the electrons are transferred, exists in Ionic bonding* Lets Bond

Which combination of atoms can form a polar covalent bond? a. H and H b. H and Br c. N and N d. Na and Br

Answer: Correct Answer: (b) H and Br Not (4) Na and Br because Na is a metal, meaning the two would form an ionic bond Lets Bond

What is the total number of electrons shared in a double covalent bond? a. 1 b. 2 c. 3 d. 4

Answer: (d) 4 There are two electrons shared within each pair Lets Bond

Which molecule will have a double covalent bond? a.F 2 b.O 2 c.Cl 2 d.N 2

Answer: (b) O 2 This is because oxygen already has four valence electrons and needs four more to have a stable octet. Therefore it shares two pairs of electrons giving it 8 electrons total Lets Bond

The degree of polarity of a chemical bond in a molecule of a compound can be predicted by determining the difference in the a. Melting points of the elements in the compound b. Densities of the elements in the compound c. Electronegativity's of the bonded atoms in the molecule of the compound d. Atomic masses of the bonded atoms in a molecule of the compound

Answer: (c) Electronegativity's of the bonded atoms in a molecule of the compound Lets Bond
