Question

D,A,L and Q are $$16th$$ group elements of Modern periodic table. The correct trend of volatality of their hydrides is $$H2D$$ > $$H2A$$ > $$H2L$$ > $$H2Q$$. The element ‘L’ in the sequence is

Down the group as the size of the atom increases affinity of hydrogen towards central atom decreases. $$Thereforea)$$ $$X-H$$ bond enthalpy decreases….$$O-H$$>$$S-H$$>$$Se-H$$>$$Te-H$$;$$b)$$ Thermal stability decreases….$$H2O$$>$$H2S$$>$$H2Se$$>$$H2Te$$;$$H2O$$ and $$H2S$$ are exothermic products, remaining three hydrides are endothermic products.$$c)$$ Reducing power increases…..$$H2OH2S$$>$$H2Se$$>$$H2Te$$;Down the group as vanderwaal's forces increasesMelting and boiling points increasesExpected BP and MP….$$H2OH2S$$>$$H2Se$$>$$H2Te$$;

D,A,L and Q are 16^th group elements of Modern periodic table. The correct trend of volatality of their hydrides is H₂D > H₂A > H₂L > H₂Q. The element ‘L’ in the sequence is
