Question

Based on their molecular structure, identify the stronger acid from each pair of oxyacids. Match the words in the left column to the appropriate blanks in the sentences on the right.

1) HI is a stronger acid than H2Te because iodine____than tellurium.
2) H2Te is a stronger acid than H2S because the H-Te bond is_____.
3) NaH is not acidic because hydrogen____than sodium.
a. has a more negative electron afflity
b. is more electronegative
c. has a larger atomic radius
d. stronger
e. is harder to ionize

Answer 1

The stronger acid can be determined by considering the electronegativity and bond strength of the elements. HI is stronger than H2Te due to iodine's higher electronegativity. H2Te is stronger than H2S due to the weaker H-Te bond. NaH is not acidic because hydrogen is less electronegative than sodium.

Step-by-step explanation:

Based on their molecular structure, the stronger acid can be determined by considering factors such as electronegativity, atomic radius, and ionization potential. In the given pairs:

HI is a stronger acid than H2Te because iodine is more electronegative than tellurium. (b) is the correct answer.

H2Te is a stronger acid than H2S because the H-Te bond is weaker than the H-S bond. (d) is the correct answer.

NaH is not acidic because hydrogen is less electronegative than sodium. (c) is the correct answer.

Answer 2

1)is more electronegative

2)

3) is more electronegative

Step-by-step explanation:

1) for the first question, iodine is more electronegative than tellurium hence we naturally expect that HI should be more acidic than H2Te since electronegativities play a role in the acidity of chemical species.

2) the correct option is not listed because the H2Te bond is weaker than the H2S bond. This makes it easier for H2Te to dissociate releasing H^+ , thereby being more acidic than H2S.

3) Hydrogen is more electronegative than sodium hence it cannot be ionized thus NaH is not acidic.
