The alkanes are a homologous series with a structure based on a carbon chain - each carbon atom forms four covalent bonds The intermolecular forces vary between molecules, so different organic ...

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 ...

“We aim to clarify what a covalent bond is—specifically ... observed such an early-career prediction in the ubiquitous carbon atom. Indeed, the ramifications for things like nanomaterials ...

A substance that contains polar covalent bonds may not be overall polar. This is due to the shape of the molecule. Water molecules are polar molecules. Both of the bonds inside the molecule are ...

Amino acids are characterized by their central carbon atom, known as the α-carbon ... Amino acids can be joined together through peptide bonds to form peptides and proteins. A peptide bond is a ...

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 ...
