Compound A (C8H10) when treated with hydrogen and palladium produces compund B (C8H18).Hydration of A produces a compund C (C8H14O2).Ozonolysis of A with an oxidative work-up produces three fragments,HOCOOH,HOCOC(CH3)2COOH,and HOCOCCH3.What are the structures of the compund A,B,C?
Hardness in groundwater is due to the presence of metal ions, primarily Mg2 and Ca2 . Hardness is generally reported as ppm CaCO3 or mmol/L Ca2
