Barron's AP Bio and the C-H bond

<p>Barron's AP Bio book goes against conventional wisdom here and claims the C-H bond is polar.</p>

<p>It is slightly polar, but the electronegativity difference is small enough for it to be considered non-polar (2.5-2.1=0.4). 0.4 is considered non-polar. </p>

<p>Yup, its def considered nonpolar (campbell & reece)</p>

<p>Any bond between two different elements will invariably have some degree of polarization. But an electronegativity difference of less than 0.5 is usually considered nonpolar, so that’s probably an error in the book.</p>

<p>Any bond that is not between two identical atoms has some polarity, as if the atoms have even the slightest bit difference in electronegativity, the electrons will be shared a little unevenly.</p>
