2020年11月19日 · Carbon suboxide with a chemical formula C 3 O 2 is a long known stable dioxide of carbon. 1 Early spectroscopic and electron diffraction investigations suggest that the molecule has a symmetrical linear structure. 2, 3 The bonding was conventionally described in common textbooks as linear cumulene valence structure O=C=C=C=O involving four doubl...

Carbon suboxide, C 3 O 2, is a foul-smelling lacrimatory (tear-stimulating) gas produced by the dehydration of malonic acid, CH 2 (COOH) 2, with P 4 O 10 in a vacuum at 140 to 150 °C (284 to 302 °F). Carbon suboxide is a linear symmetrical molecule whose structure can be represented…

2014年12月10日 · They find that pi and total bonds are less for C-C and more for C-O, and that the central C and the Os have negative change while the outer two Cs have positive change. This list reflects these findings. The structure you proposed would not fit well with those findings.

Hydroxyacetone, also known as acetol, is the organic chemical with the formula CH 3 C (O)CH 2 OH. It consists of a primary alcohol substituent on acetone. It is an α -hydroxyketone, also called a ketol, and is the simplest hydroxy ketone structure. It is a colorless, distillable liquid. It is produced commercially by dehydration of glycerol. [4]
