Learn about saturated compounds with maximum hydrogen atoms and single C-C bonds, and unsaturated compounds with double or triple C-C bonds. Alkenes have at least one double bond, while alkynes contain a triple bond. Discover how to name alkenes and alkynes based on their structure.

Chapter 25 Section 2 saturated compounds- contain max # of H -all alkanes, all single C-C bonds unsaturated compounds- do not contain max # of H -contain double or triple C-C bonds -not saturated with hydrogen -alkenes and alkynes Alkenes -contain at least one double C═C bond
Naming Alkenes • Find longest chain containing double bond -this is parent chain -gets –ene ending ex- butene • # so that C atoms of the double bond get the lowest #’s, then look at alkyl groups to get lowest # -double bond gets numbered in the name ex- 2-butene
Substituents get named the same as alkanes ex- 2-methyl • Put all together ex: 2-methyl-2-butene Alkynes -contain triple bond -named same way except end in –yne
