Which of the following is the molecular formula for butane?

Which of the following is the molecular formula for butane?

Step 1: Understand that butane is a type of hydrocarbon, which means it is made up of carbon (C) and hydrogen (H) atoms.
Step 2: Know that butane is an alkane, which is a specific type of hydrocarbon that follows the formula CnH(2n+2), where n is the number of carbon atoms.
Step 3: For butane, n equals 4 because butane has 4 carbon atoms.
Step 4: Plug n = 4 into the formula CnH(2n+2): C4H(2*4+2).
Step 5: Calculate the number of hydrogen atoms: 2*4 + 2 = 8 + 2 = 10.
Step 6: Therefore, the molecular formula for butane is C4H10.
