Identify the correct order of solubility in aqueous medium :
Aqueous solutions of two compounds $$M-O-H$$ and $$M'-O-H$$ have been prepared in two different beakers. If the electronegativity of $$M= 3.5,\ M' = 1.72,\ O = 3.0$$ and $$H = 2.1$$, then the solutions respectively are:
Aqueous solutions of two compounds $$M_1 -O-H$$ and $$M_ 2-O-H$$ are prepared in two different beakers. If, the electronegativity of $$M, =3.4,M.2 =1.2,O =3.5$$ and $$H =2.1$$, then the nature of two solutions will be respectively :
Water is an oxide of hydrogen represented by the formula $$H_2O$$. However, the oxide of fluorine is represented by the formula $$OF_2$$ and not $$F_2O$$. How do you justify this?
HAO is the compound whose aqueous solutions is basic and order of basic strength is____.
On the basis of percent ionic character for the compounds $$CD$$ & $$AB$$, they will be colourless. If true enter 1, else enter 0.
