What is the difference in molar mass of any two neighbouring alkanes?

Options

  1. A12 ~g ~mol ⁻¹
  2. B10 ~g ~mol ⁻¹
  3. C15 ~g ~mol ⁻¹
  4. D14 ~g ~mol ⁻¹

Correct answer

D. 14 ~g ~mol ⁻¹

Step-by-step solution

Mention that -CH2 unit is added when we move b/w succesive hydrocarbons . That is why 14g mass difference is always there b/w succesive hydrocrbons in same monolgue series.
