Answer and explanation

Correct answer: C. C_n H_(2n + 2)

  1. Step 1: Alkanes are saturated hydrocarbons containing only single C-C and C-H bonds. Step 2. Their general formula is C_n H_(2n + 2) (e.g., methane CH4, ethane C2H6, propane C3H8). Answer: C_n H_(2n + 2). Why not the others: C_n H_2n is the formula for alkenes.
