Methane, Ethane, Propane, Butane, Pentane ...

In this video we'll at Methane (CH4), Ethane (C2H5), Propane (C3H8), Butane (C4H10), Pentane (C5H12) and other alkanes as well as their chemical formulas. Methane’s formula follows the general pattern for alkanes. Alkanes are hydrocarbons and made up of Carbon and Hydrogen atoms. All alkanes, including methane, follow the formula CnH2n+2. The n is the number of carbons. For example, for Methane we have C1H2(1) +2 or CH4. Which is the the chemical formula for methane. I recommend that you commit prefixes for each of the first ten alkanes to memory since they are is often used in examples and problems. of C Atoms Molecular Formula Name 1 CH4 methane 2 C2H6 ethane 3 C3H8 propane 4 C4H10 butane 5 C5H12 pentane 6 C6H14 hexane 7 C7H16 heptane 8 C8H18 octane 9 C9H20 nonane 10 C10H22 decane More chemistry at http://www.Breslyn.org
