• Molecule Shapes

  23832 Molecule Shapes What shape do you expect for molecules that meet the following descriptions? a) A central atom with two lone pairs and three bonds to other atoms. b) A central atom with two lone pairs and two bonds to other atoms.

• Bonding in N2 and N2H4

  The Lewis structures for these two molecules are: In regular nitrogen, N2, there is a triple bond. This means there are two pi-bonds (extra bonds). Each pi-bond requires a p-orbital that is not involved in hybridization.

• Reactivity of Organic Compounds

  are sigma and pi- bonds and triple bond between C and C atoms.

• Biological and Chemical Diversity

  The rigid planarity imposed by double bonds has enormous significance for the shape of large biological molecules such as proteins and nucleic acids. (In triple bonds, two atoms share six electrons. These are rare in biological molecules.)

• Could Silicon replace Carbon in Organic Chemistry?

  One would be hard pushed to find any molecules that have a large number of silicon atoms bound together (e.g. more than three silicon atoms is very rare).

• Carbon structure, bonds of carbon.

  The carbon structure and bonds of carbon are determined. The structures of two hydrocarbons and one biochemical molecules are named.

• Geometric Structure and Localized Bonding Models

  Theoretical chemists have explored the possible existence of other polynitrogen species, including neutral molecules of composition N4. Write Lewis structures for two different molecules with this composition.

• Compound or a mixture

  Mixtures are composed of variable proportions of molecules and atoms. Compounds are homogeneous forms of matter.

• Protein and Elements in Solution

  When two atoms join together, they form a molecule. Some molecules are made up of covalent bonds, but since some are also made up of ionic bonds, the correct answer is "molecule." That's a bit of a tricky question. 5.
