forms 4 single covalent bonds with other atoms//
 * Saturdated Hydrocarbons**: //are hydrocarbons in which each carbon atom

-Only Single Bonds -Known as Alkanes

-Carbon atoms in a ring -Named with cyclo- prefix
 * Cycloalkanes**

-Straight chain= prefix -ane -Cyclo= cyclo-prefix-ane -Radicals= prefix-yl radical
 * Nomenclature**

1. Name longest continuous chain 2.ID and name alkyl groups (the branches) - alphabetical order - use prefixes if multipule ( di/tri/ etc.) 3.Assign position numbers to each branch
