the structure below is __________.
h h h h

h - c - c - c - c - h

h h h h
a) methane
b) propane
c) pentane
d) hexane
e) butane

Explanation:

• Methane ($CH_4$) has 1 carbon atom.
• Propane ($C_3H_8$) has 3 carbon atoms.
• Pentane ($C_5H_{12}$) has 5 carbon atoms.
• Hexane ($C_6H_{14}$) has 6 carbon atoms.
• Butane ($C_4H_{10}$) has 4 carbon atoms. Counting the carbon atoms in the given structure (4 carbons), it matches the formula of butane.

Answer:

e) butane
