Question

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?

• Ethane is nonpolar because it has an even distribution of charge across the entire molecule, which results from the large electronegativity difference between the carbon and hydrogen atoms.
• Ethane is nonpolar because it has an even distribution of charge across the entire molecule, which results from the small electronegativity difference between the carbon and hydrogen atoms. 
• Ethane is nonpolar because it has an uneven distribution of charge across the entire molecule, which results from the small electronegativity difference between the carbon and hydrogen atoms.
• Ethane is nonpolar because it has an uneven distribution of charge across the entire molecule, which results from the large electronegativity difference between the carbon and hydrogen atoms.

it's NOT: the bolded option (bullet point #1)

Answer 1

• Ethane is nonpolar because it has an even distribution of charge across the entire molecule, which results from the small electronegativity difference between the carbon and hydrogen atoms.
