WebBond lengths for paraffinic C–O bonds are in the range of 143 pm – less than those of C–N or C–C bonds. Shortened single bonds are found with carboxylic acids (136 pm) due to partial double bond character and elongated bonds are found in epoxides (147 pm). The C–O bond strength is also larger than C–N

WebThe N–O stretching vibrations in nitroalkanes occur near 1550 cm -1 (asymmetrical) and 1365 cm -1 (symmetrical), the band at 1550 cm -1 being the stronger of the two. If the nitro group is attached to an aromatic ring, the N–O stretching bands shift to down to slightly lower wavenumbers: 1550-1475 cm -1 and 1360-1290 cm -1. Summary: WebThe infrared stretching frequencies of these groups vary in the same order, ranging from 1100 cm -1 for C-N, to 1660 cm -1 for C=N, to 2220 cm -1 for C≡N.
