WebbTherefore, this article mainly discusses the following two aspects: (1) The activation and cleavage of C―O bonds, which includes total and selective C―O bond cleavage in furan-based fuel precursors and lignin. When aiming to produce liquid fuels, including alkanes and arenes from biomass, the total cleavage of C―O bonds is essential. WebbFor example, a C=N double bond is about twice as strong as a C-N single bond, and the C≡N triple bond is similarly stronger than the double bond. The 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. Approximate Infrared Stretching Frequencies.
WebbCN- has sp hybridization. CN- is polar in nature. There are two elements involves in the formation of CN- lewis structure i.e. nitrogen (N) and carbon (C) which is connected by triple bonds. In CN- lewis structure, it has two lone electron pairs one each on carbon and nitrogen atoms.

The number of bonded atoms determines the Bond angle. A larger bond angle would be the result of less repulsion. Since CN- only has two atoms, it has linear geometry. The bond angle of cyanide ion (CN-) will be 180 degrees. The Polarity of CN– (Is CN– Polar or …
