Questions & Step-by-Step Solutions

Which of the following is the correct formula for an alkane?
  • Step 1: Understand what an alkane is. An alkane is a type of hydrocarbon that consists only of carbon (C) and hydrogen (H) atoms.
  • Step 2: Learn the general formula for alkanes. The formula is C_nH_{2n+2}, where 'n' represents the number of carbon atoms in the alkane.
  • Step 3: Identify the number of hydrogen atoms. For every carbon atom (n), you can calculate the number of hydrogen atoms using the formula 2n + 2.
  • Step 4: Use the formula to find the correct structure of an alkane based on the number of carbon atoms you have.
