How would I determine the electronegativity of Ethanol?

As far as I know you don't. EN is a term and number for elements, not compounds. You may be thinking of polarity. Ethanol is somewhat polar.

To determine the electronegativity of ethanol, you can refer to the electronegativity values of its constituent elements. Ethanol (C2H5OH) is composed of carbon (C), hydrogen (H), and oxygen (O). Electronegativity is a measure of an atom's ability to attract electrons in a chemical bond.

First, you need the electronegativity values of carbon (C), hydrogen (H), and oxygen (O). You can find these values on the periodic table or in various reference materials focused on chemistry.

Next, calculate the average electronegativity of the atoms present in ethanol. This is done by summing up the electronegativity values of each atom and dividing by the total number of atoms.

For example, let's use the Pauling scale (a common scale for measuring electronegativity):

- Carbon (C) has an electronegativity value of 2.55.
- Hydrogen (H) has an electronegativity value of 2.20.
- Oxygen (O) has an electronegativity value of 3.44.

To determine the average electronegativity:

(2.55 + 2.20 + 3.44) / 3 = 2.73.

Therefore, the estimated electronegativity value of ethanol is approximately 2.73 on the Pauling scale.

It's important to note that electronegativity can vary depending on the context and scale used, so different sources may provide slightly different electronegativity values.
