SAT Writing Section Questions Practice Test Passage Title: The Effects of Electronegativity

 1  What principles dictate the relationships between molecules? There are many factors at work, but these interactions also depend indirectly on a principle known as electronegativity. Although this is an atomic property,  it generates molecular  forces that cause many of the phenomena we observe every day.

 3  Electronegativity, the measure of an atom’s affinity for electrons, generally determines the type of bond present between two atoms.  A single bond between atoms consists of two electrons. If the two atoms have similar electronegativities, they share the two electrons equally and form a nonpolar covalent bond. If two atoms have significantly differing values of electronegativity, there are two possible bond types: polar covalent and ionic. While other factors also  4  corrupt the determination of bond type, a difference in electronegativity between the values of 0.5 and 1.6 usually  result in a polar covalent bond, while a difference of more than 2.0 usually results in an ionic bond.

In a polar covalent bond, the two bonding electrons are 6 shared  unequally, in an ionic bond:  both electrons are completely transferred to the more electronegative atom. For example, the bond between oxygen (O) and hydrogen (H) is classified as a polar covalent bond, because they share the two bonding electrons unequally. This polar bond type is partially caused by the difference in electronegativities:  7  hydrogen has an electronegativity of 2.20, while oxygen has an electronegativity of 3.44. When the electronegativity of the hydrogen is subtracted from the electronegativity of the oxygen, the difference is 1.24.

When a hydrogen atom is bonded to nitrogen, oxygen, or fluorine, this particular polar covalent bond makes that a new type of interaction possible: hydrogen bonding. For instance, a water molecule consists of an oxygen atom bonded to two hydrogen atoms. The unequal sharing of electrons causes a distribution of partial charges on the molecule. The oxygen of one water molecule monopolized the bonding electrons and acquires a partial negative  charge; as a result, this oxygen atom is attracted to the partially positive hydrogen atoms of another water molecule.

This electrostatic attraction,  9  which is an attraction referred to as intermolecular hydrogen bonding, contributes to the surface tension that sustains the weight of water striders and some other insects. 

10  The presence of surface tension in water is just one result of the hydrogen bonding. From digestion to DNA structure, this molecular force is integral  11  with many life-sustaining processes. If atoms did not have different values of electronegativity, hydrogen bonding would be impossible—and life as we know it could not exist.

Option C : How do our bodies break down the food we consume every day? While digestion would be impossible without enzymes and other proteins, these molecules

Option D : How does our DNA maintain a double helical structure? While the shape of this nucleic acid is the result of many complex properties, its structures

Answer

Show/Hide Answer

Option B: How do water striders skim across the surfaces of ponds and lakes? Their hydrophobic legs are uniquely suited to this process, but the insects

Question No 2

Option C : forces

Option D : forces;

Answer

Show/Hide Answer

Option C : forces

Question No 3

The writer is considering deleting the underlined sentence. Should the writer make this deletion?

Option A : Yes, because the sentence unnecessarily repeats a definition provided earlier in the passage.

Option B : Yes, because the sentence is not relevant to the paragraph’s discussion of historic experiments that depended on electronegativity

Option C : No, because the sentence introduces the paragraph’s discussion of the relationship between electronegativity and bond type.

Option D : No, because the sentence provides an effective transition to the paragraph’s explanation of hydrogen bonding.

Answer

Show/Hide Answer

Option C : No, because the sentence introduces the paragraph’s discussion of the relationship between electronegativity and bond type.

Option A : No Change

Option B : are resulting

Option C : results

Option D : have resulted

Answer

Show/Hide Answer

Option C : have resulted

Question No 6

Question No 7

Which choice most effectively uses accurate and relevant data from the graph in the passage to illustrate the concept being explained?

Option A : No Change

Option B : at 5.5, hydrogen has one of the highest electronegativity numbers on the Pauling electronegativity scale.

Option C : the electronegativity of oxygen is 3.44, a value significantly lower than that of hydrogen.

Option D : because their electronegativities lie in the 3 to 3.5 range, both oxygen and nitrogen are capable of helping cause a force known as ‘hydrogen bonding.
