23 sty 2023 · This is an introductory page about alkanes, such as methane, ethane, propane, butane and the remainder of the common alkanes. This page addresses their formulae and isomerism, their physical properties, and an introduction to their chemical reactivity.
Alkanes are saturated hydrocarbons. By saturated hydrocarbons, it means alkanes have single hydrogen and carbon atoms in their chemical formula. Formula of alkane is C n H 2n+2. Methane, propane, ethane, and butane are four alkanes. Let us learn in detail about Alkanes and their physical properties below. Suggested Videos.
Methane (CH4), ethane (C2H6), propane (C3H8) and butane (C4H10) are the first four alkanes. Methane gas, whose molecular formula is CH4, is the simplest alkane.
This is an introductory page about alkanes, such as methane, ethane, propane, butane and the remainder of the common alkanes. This page addresses their formulae and isomerism, their physical properties, and an introduction to their chemical reactivity.
Methane (CH 4), ethane (C 2 H 6), and propane (C 3 H 8) are the beginning of a series of compounds in which any two members in a sequence differ by one carbon atom and two hydrogen atoms—namely, a CH 2 unit. The first 10 members of this series are given in Table \(\PageIndex{1}\).
Methane, ethane, propane, and butane all belong to the class of organic compounds that are called alkanes. The general chemical formula for alkanes is C n H 2n+2 . From this general formula, we see that the alkane is methane (CH 4 ) for n = 1, ethane (C 2 H 6 ) for n = 2, propane (C 3 H 8 ) for n=3, and so on and so forth.
The names, molecular formulae and the structural formulae of the first eight alkanes must be learned. Using a mnemonic can make learning the names easier.
