Among the following, which is the correct statement?
Show Hint
Electron-precise hydrides are formed by elements in group 14 because they have four valence electrons and form stable bonds with these electrons.
Updated On: May 14, 2025
- Saline hydrides react slowly with water
- All elements of group 14 form electron-precise hydrides
- BaCl\(_2\).2H\(_2\)O has hydrogen bonded water
- Density of ice is more than that of water
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
- Saline hydrides are known to react quickly with water, not slowly. Hence, option (1) is incorrect.
- Group 14 elements (e.g., Si, Ge, Sn, Pb) form electron-precise hydrides, making option (2) correct.
- BaCl\(_2\).2H\(_2\)O involves water of crystallization, not hydrogen-bonded water. Hence, option (3) is incorrect.
- The density of ice is less than that of water, not more, making option (4) incorrect.

- $\mathrm{BF_3 + NaH}$
- Consider the following statements:
Statement-I: H$_2$Se is more acidic than H$_2$Te.
Statement-II: H$_2$Se has higher bond dissociation enthalpy than H$_2$Te.
In light of the above statements, choose the correct option: A group 15 element forms \( d\pi - d\pi \) bond with transition metals. It also forms a hydride, which is the strongest base among the hydrides of other group members that form \( d\pi - d\pi \) bonds. The atomic number of the element is …….
