WebNov 28, 2024 · C and H have very similar electronegativities, causing their bond to be considered a nonpolar covalent bond. The reason why they are so far apart is because of their difference in electrons in the valence shell. It makes more sense for H to be in group 1 because it was 1 electron in the valence shell, resulting in it being so far apart from C. Top WebIn organic compounds the C-C and C-H bonds are regarded as non-polar since the electronegativities are similar C (2.5) and H (2.1) Most bonds within organic molecules will be covalent.

WebFirst of all, the difference in the electronegativities of carbon (2.55) and hydrogen (2.2) is roughly 0.35. The C − H bond is indeed slightly more polar than the C − C bond, but this …
