Alicyclic hydrocarbons Cycloalkanes, Cycloalkenes

Alicyclic Hydrocarbons. These refer to cyclic analogues of aliphatic hydrocarbons and are named accordingly, using the piefix cyclo-." Their properties are similar to their open-chain aliphatic counterparts. Alicyclic hydrocarbons are subdivided into monocyclic (cycloalkanes, cycloalkenes, cycloalkynes, cycloalkadienes, etc.) and polycyclic aliphatic compounds. Monocyclic aliphatic structures having more than 30 carbon atoms in the ring are known, but those containing 5 or 6 carbon atoms are more commonly found in nature [47, p. 28]. 

Other alicyclic hydrocarbons have the same kind of properties as their open-chain counterparts, and they are characterized in the same way cycloalkanes by their general inertness, and cycloalkenes and cycloalkynes by their response to... 

Alicyclic (Section 4.1) An aliphatic cyclic hydrocarbon such as a cycloalkane or cycloalkene. 

In this chapter we shall take up the alicycUc hydrocarbons (a//phadc cyclic hydrocarbons). Much of the chemistry of cycloalkanes and cycloalkenes we already know, since it is essentially the chemistry of open-chain alkanes and alkenes. But the cyclic nature of some of these compounds confers very special properties on them. It is because of these special properties that, during the past fifteen years, alicyclic chemistry has become what Professor Lloyd Ferguson, of the California State College at Los Angeles, has called the playground for organic chemists. It is on some of these special properties that we shall focus our attention. 

Cycloalkanes - Saturated monocyclic hydrocarbons (with or without side chains). See alicyclic compounds. Unsaturated monocyclic hydrocarbons having one endocyclic double or one triple bond are called cycloalkenes and cycloalkynes, respectively. [5]...
