  • question_answer
    Least thermally stable is - 

    A) \[CC{{l}_{4}}\]            

    B) \[SiC{{l}_{4}}\]

    C) \[GeC{{l}_{4}}\]                      

    D) \[GeB{{r}_{4}}\]

    Correct Answer: D

    Solution :

    [d] The thermal stability of tetrahalides decreases in order \[C{{X}_{4}}>Si{{X}_{4}}>Ge{{X}_{4}}>Sn{{X}_{4}}\] and in terms of same metal with different halides is in order of \[M{{F}_{4}}>MC{{l}_{4}}>MB{{r}_{4}}>M{{I}_{4}}.\]
