Complete the sentences to explain your reasoning.

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

1-b

2-weaker(option is incorrect)

3-a

Explanation:

1-b because iodine is more electronegative because of this negative on iodine will be more stable as negative charge on more electronegative element is more stable.

2-weaker as size of Te (Tellurium) is greater than S (sulphur) so bond length of H-Te is larger than H-S and therefore bond energy will be lesser and can easily give hydrogen in case of H-Te. as bond energy is inversly proportional to bond length.

3-a hydrogen has more negative electron affinity so hydrogen will have -1 charge and it will behave as a electron donar atom that is basic not acidic hence NaH is not acidic.

the answers would be

the first one and the second one
