Vedclass · Answer

(D) Saline hydrides,also known as ionic or salt-like hydrides,are formed by the reaction of $s$-block elements with dihydrogen at high temperatures. They are stoichiometric compounds consisting of a metal cation and a hydride anion $\left( H^- \right)$. Because they are ionic,they possess high melting points and conduct electricity in the molten state. They react vigorously with water to produce hydrogen gas and are strong reducing agents. Therefore,the statement that they are covalent in nature is incorrect.
