WebThe alkali metals form salt-like hydrides by the direct synthesis at elevated temperature. The thermal stability of these hydrieds decreases in which of the following orders? CsH > RbH … WebCsH > RbH > KH> NaH> LiH KH > NaH > LiH >CsH > RbH NaH> LiH> KH>RbH > CsH LiH> NaH> KH>RbH > CsH The stability of alkali metal hydrides decreases from Li to Cs. It is due to the fact that M–H bonds becomes weaker with increase in size of alkali metals as we move down the group from Li to Cs. Thus the order of stability of hydrides is (D).
