Question
Which of the following compounds is not an alkane?*1 pointC₆H₁₄C₁₃H₂₈C₁₈H₃₆C₁₉H₄₀
Solution
The formula for alkanes follows the general formula CnH2n+2.
- C₆H₁₄: This follows the formula (2*6)+2 = 14
- C₁₃H₂₈: This follows the formula (2*13)+2 = 28
- C₁₈H₃₆: This follows the formula (2*18)+2 = 38, but given is 36, so it does not follow the formula.
- C₁₉H₄₀: This follows the formula (2*19)+2 = 40
So, C₁₈H₃₆ is not an alkane.
