    The elements X,V and Z form oxides which are acidic, basic and amphoteric respectively. The correct order of their electronegativity is

    A)  \[X>Y>Z\]

    B)  \[Z>V>X\]

    C)  \[X>Z>Y\]

    D)  \[Y>X>Z\]

    Correct Answer: C

    Solution :

                     Electronegativity \[\propto \]non-metallic character\[\propto \frac{\text{1}}{\text{metallic}\,\text{character}}\] \[\because \] The element (X) form acidic oxide, so it is a non-metal, while the element (Y) form basic oxide, so (V) is a metal. Thus, the order of their electronesativity is \[X>Z>Y\]
