Question 26 :
<div>The Alsatian-Swiss chemist Alfred Werner pioneered the field of coordination chemistry in the late nineteenth century. At that time, a number of compounds of cobalt (III) chloride with ammonia were known, with general formula $$CoCl_3.xNH_3$$ $$x=3\ to\ 6$$<br/>Treatment of these compounds with aqueous HCl acid did not remove the ammonia. However, treatment of the compounds with excess of $$AgNO_3$$ at 273 K gave white precipitate of AgCl in varying ratio depending on the structure. Also each complex had electrical conductivity of varying nature.</div><div> <br/></div><div>There is no reaction of the compound with aqueous HCl indicating that there is no free $$NH_3$$. Thus, $$NH_3$$ ligand is bonded to cobalt(III) by________ .<br/></div>
