Covalent Compounds

Any covalently bonded compound containing carbon, with the exception of carbonates and oxides *Low melting and boiling points *Poor conductors of electricity *All organic compounds contain carbon but not all carbon containing compounds are organic

Alkene Formula

CnH2n

Alkane formula

CnH2n+2

Alkenes paragraph

Recall that an alkene is a hydrocarbon with one double bond between two of the carbon atoms in the chain. The alkenes follow a pattern much like that of the alkanes. The same prefix as that used for the alkanes is used to indicate the number of carbon atoms in the molecule; however, each ends in "ene". The general formula for an alkene is CnH2n

Why can you not build a model of methene?

You can't build a model of methene because "ene" (s) have double bonds; and you can't have a double bond connected to a hydrogen

Hydrocarbons

*Composed of only hydrogen and carbon *Saturated contain only single bonds (alkanes) *Unsaturated contain double bonds (alkenes) and triple (alkynes) carbon-carbon bonds very reactive because of double and triple bonds.

Alkanes and Alkenes Paragraph

Alkanes-recall that an alkane is a hydrocarbon in which each carbon atom forms single which carbon atoms form single covalent bonds with four other atoms. The name of an alkane ends in "ane", and the number of carbon atoms is indicated by a prefix: "meth-" means one carbon atom, "etc-" means two carbon atoms, "prop-" means three carbon atoms and "but-" means four carbon atoms. These are only four of many prefixes used to name alkanes. The general formula for an alkane is CnH2n+2

Molecular Compounds Paragraph

In these compounds, which are formed between nonmetals the atoms bond together to create molecules. In molecular compounds , subscripts are used to show the number of atoms of each element per molecule.

Organic Compounds

Organic compounds are now defined as compounds that contain the element carbon. The nature of the bonds between each pair of carbon atoms in an organic compound will determine whether the compound is saturated or unsaturated. The bonds between the carbon atoms in a(n) saturated compound are single bonds, but in a(n) unsaturated compound, the bonds between neighboring carbon atoms are double or triple bonds. The organic compounds containing only hydrogen and carbon are called hydrocarbons. CnH2n+2 is the general form for the alkane series of hydrocarbons. The names of this series are composed of a prefix, which denotes the number of carbon atoms present, and the suffix "ane". This series of hydrocarbons has only single bonds, and so, is said to be saturated. CnH2n is the general form for the class of hydrocarbons referred to as the alkenes. Each member of this series has a pair of carbon atoms connected by a double bond, and so, is said to be unsaturated. Again, prefixes are used to denote the number of carbon atoms present in the molecule, and all members of this series end in the suffix "ene"
