Disclosed is a composition comprising a chemical formulation useful for creating geosynthetic composites in-situ, which includes a reactive ester having at least one carbon-carbon double bond, preferably a vinyl ester of a C9 to C11 versatic acid or vinyl ester of a long chain fatty acid, or ...
A carbon-carbon double bond is twice as strong as a carbon-carbon single bond. True False True or false? Carbon atoms always form three covalent bonds. sp hybridized carbon atoms are associated with double bonds. Is the statement true or false?
athe two pairs of electrons of oxygen may be shared with one carbon alone forming a double bond, or with two separate carbons,or with one carbon and one hydrogen forming only single bonds 正在翻译,请等待... [translate]
The invention relates to novel polymeric organosilicon compounds comprising hydrocarbon radicals with at least one aliphatic carbon-carbon double bond in a terminal position. To produce these compounds, (A) compounds containing at least ... DR HERZIG,B Robert,S Reinhard,... - WO 被引量: 10发表...
6.36. The nucleophilic attack is an axial addition and takes place preferentially from the top face of the carbon–carbon double bond to give directly the chair, rather than a twist-boat from the bottom face attack (cf. Fig. 6.29). Subsequent protonation of the enolate intermediate then ...
Described are mixtures of t-mercapto terpene isomers defined according to the generic structure: <IMAGE> wherein one of the dashed lines is a carbon-carbon double bond and the other of the dashed lines is a carbon-carbon single bond taken further together with alpha -terpineol having the struc...

Oxygen pretends two of carbon's electrons belong to it, so it also has eight electrons in its outer shell. We can draw it like this: When carbon doubles up like this, we call it a double bond. That makes sense, doesn't it? 3 Carbon can also bond with itself. The only problem is...
