Vedclass · Answer

(D) Saline hydrides,also known as ionic hydrides,are formed by the reaction of $s$-block elements (alkali and alkaline earth metals) with dihydrogen at high temperatures.These hydrides are crystalline,non-volatile,and non-conducting solids in their solid state.However,they conduct electricity in the molten state due to the presence of mobile ions.They react violently with water to produce hydrogen gas,e.g.,$NaH + H_2O \rightarrow NaOH + H_2$.They act as strong reducing agents.Since they are ionic in nature,the statement that they are covalent is incorrect.

Which of the following statements is incorrect regarding saline hydrides?
