The atoms form a double bond because there is a strong enough attraction in both directions and room for the electrons in the outer energy level of the atoms. The carbon atom and hydrogen atoms are ...

This time, the Japanese scientists used a chemical reaction (oxidation) to remove an electron from an existing two-electron covalent bond between two carbon atoms. A large hydrocarbon molecule was ...

The redox reactions affect the number of covalent bonds that a carbon makes to a heteroatom substituent, such as nitrogen and oxygen. Each redox state of carbon (Fig. 2) is associated with a class ...

Carbon tetrachloride has four polar covalent bonds. It is a tetrahedral molecule, so the charges are symmetrical. The \(\delta+\) part of the molecule (the carbon atom) is locked away at the ...

The ball-and-stick and first space-filling model show that sucrose is a large molecule made up of carbon, oxygen, and hydrogen. Sucrose has many O–H bonds which are polar. These polar areas are shown ...
