Which bond has the lowest polarity?
a) C-H bond in methane, CH4
b)C=O bond in Carbon dioxide, CO2
c)C-C bond in ethane, C2H6
d)C-C in ethanol, C2H5OH
any explanation would be very appreciated if you have time.
Thank you!!
thanks gymnast, great explanation. you'll be getting the best answer.

The C-C bond in ethane is the lowest polarity.
Polarity is determined by the different in electronegativities.
Two carbons have an electronegativity difference of zero. So carbon carbon bond has the smallest polarity.
That narrow it down to ethane and ethanol.
In ethanol the carbon is connected to different substituents.
C1 is connected to 3 H's and the C2 is connected 2 H's and an OH
The different in electron density makes the C-C bond in ethanol more polar.

C
They both are identical (both carbons are bonded with the other carbon and 3 other hydrogens) so the electronegativity between the two carbons must be identical.
