Ethane (C2H6) has one C-C bond and six C-H bonds. The electronegativity difference between carbon and hydrogen is less than 0.4.
What is a property of ethane?
Unless you have choices that you did not post, here is something from Google:
Properties. At standard temperature and pressure, ethane is a colorless, odorless gas. It has a boiling point of −88.5 °C (−127.3 °F) and melting point of −182.8 °C (−297.0 °F). ... Ethane is only very sparingly soluble in water.
A property of ethane (C2H6) is that it is a colorless, odorless gas at room temperature and pressure. It is a nonpolar molecule because it has a symmetrical structure and the electronegativity difference between carbon and hydrogen is less than 0.4.
To determine this property, you can first identify the molecular formula of ethane, which is C2H6. From this formula, you can determine the number of carbon-carbon (C-C) bonds and carbon-hydrogen (C-H) bonds present in the molecule. Ethane has one C-C bond and six C-H bonds.
Next, you can consider the electronegativity difference between carbon and hydrogen. Electronegativity is a measure of an atom's ability to attract shared electrons in a chemical bond. In ethane, since the electronegativity difference between carbon and hydrogen is less than 0.4, it indicates that the C-H bond is nonpolar.
Based on this information, one can deduce that the property of ethane being a colorless, odorless gas at room temperature and pressure is attributed to its nonpolar nature.
