Write the order of thermal stability of the hydrides of Group 16 elements. |
|
Answer» Solution :As the SIZE of the element increases down the group , the E-H (E stands for elements of Group 16 ) bond dissociation energy decreased and henced E-H bond BREAKS more easily . Thus, the thermal stability of the HYDRIDES of Group 16 elements decreases down the Group : `H_2O gt H_2S gt H_2Se gt H_2Te gt H_2Po`. |
