Which of the following elements is mismatched with its properties or functions? a) carbon-forms the backbone of organic compounds, b) nitrogen-component of proteins, c) hydrogen-very electronegative, d) Oxygen-can participate in hydrogen bonding, e)all of the above are correctly matched..

The element that is mismatched to its properties or function is the hydrogen- very electronegative (option C).

Explanation:

Electronegativity is a property that consists of the power of attraction of electrons that an element has. Hydrogen has an electronegativity of 2.1, which is lower than that of carbon, so it is not a very electronegative element.

In the other options, the element and its function do match:
