NettetAnswer (1 of 2): Contrary to the question ionic nature of alkali metals hydrides increase down the group.. Reasons * LiH is more covalent, this is due high polarising power of Li because of its small size * CsH is more ionic as the size of the cation increases the ionic nature increases for h... NettetLiH>NaH> KH >RbH>CsH. The stability of alkali metal hydrides decreases with increase in the size of the metal cation. ... Metal hydrides are ionic, covalent or molecular in nature. Among L i H, N a H, K H, R b H and C s H, the correct order of increasing ionic character is: Q. Match the following. A) Thermal stability order of hydrides 1) ...

NettetLiH, NaH and CsH in order of increasing ionic character. H - H, D - D and F - F in order in order of increasing bond dissociation enthalpy. N a H, m g H 2 and H 2 O in order of increasing reducing property. NettetSolution: Option (ii) is the answer. As we advance down the group, the ionic nature rises. As ionisation enthalpy drops from top to bottom in a group, metal tends to lose electron. So ionic character grows. get the soap
