Answer:
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 Complete sentences is :
Answer 1.
b. is more electronegative
- HI is a stronger acid than H2Te because iodine is more electronegative than tellurium.
- This is because iodine has a higher electronegativity and this negative charge is more stable to iodine. Negative charges are more stable for elements with higher electronegativity.
2.) H2Te is a stronger acid than H2S because the H-Te bond is Stronger .
- Therefore, the bond length of H2Te is longer than that of HS, the binding energy is high and in the case of H2Te, it is easier to generate hydrogen. This is because the binding energy is inversely proportional to the bond length.
3.) NaH is not acidic because hydrogen has a more negative electron afflity than sodium.
- A Hydrogen has a more negative electron affinity, so it has one charge and behaves like a basic, non-acidic electron-donating atom. Therefore, NaH is not acidic.
