What is the molecular formula for butane?
A
B
C
D
Verified step by step guidance1
Identify the type of hydrocarbon butane is. Butane is an alkane, which means it is a saturated hydrocarbon containing only single bonds between carbon atoms.
Recall the general molecular formula for alkanes, which is \(C_nH_{2n+2}\), where \(n\) is the number of carbon atoms.
Determine the number of carbon atoms in butane. The prefix 'but-' indicates that there are 4 carbon atoms, so \(n = 4\).
Substitute \(n = 4\) into the alkane formula to find the number of hydrogen atoms: \(H = 2(4) + 2\).
Write the molecular formula for butane using the values found: \(C_4H_{10}\).
