Alkanes
|
Alkanes (also known as paraffins or saturated hydrocarbons) are chemical compounds that consist only of hydrogen and carbon atoms and are bonded exclusively by single bonds (i.e., they are saturated compounds) without any cycles (or loops; i.e., cyclic structure). Alkanes belong to a homologous series of organic compounds in which the members differ by a constant relative molecular mass of 14. Each carbon atom must have 4 bonds (either C-H or C-C bonds), and each hydrogen atom must be joined to a carbon atom (H-C bonds). A series of linked carbon atoms is known as the carbon skeleton or carbon backbone. In general, the number of carbon atoms is often used to define the size of the alkane (e.g., C2-alkane). An alkyl group, generally abbreviated with the symbol R, is a functional group or side-chain that, like an alkane, consists solely of single-bonded carbon and hydrogen atoms, for example a methyl or ethyl group. The simplest possible alkane (the parent molecule) is methane, CH4. There is no limit to the number of carbon atoms that can be linked together, the only limitation being that the molecule is acyclic, is saturated, and is a hydrocarbon. Saturated oils and waxes are examples of larger alkanes where the number of carbons in the carbon backbone tends to be greater than 10. Alkanes are not very reactive and have little biological activity. Alkanes can be viewed as a molecular tree upon which can be hung the interesting biologically active/reactive portions (functional groups) of the molecule. From Wikipedia under the

And oh, if it's not too demanding, can I ask the same question again, only now it's the behavior of alkenes instead of alkanes. Thanks again!

Besides, when you take organic chemistry, it's really helpful to have a set of condensed notes. :-) Answered by T.J. - Thu Aug 31 00:00:50 2006 What two stereoisomeric alkanes are formed in the catalytic hydrogenation of (E)-3-methyl-2-hexene?
Q. What two stereoisomeric alkanes are formed in the catalytic hydrogenation of (E)-3-methyl-2-hexene? I'm having trouble starting this problem. Can someone please outline the steps I would have to take to get an answer. Thank you. Asked by - Thu Dec 2 19:32:49 2010 - Chemistry - 1 Answers - Comments From Yahoo Answer Search: "alkanes" |
