The compound with molecular formula \(\text{C}_{20}\text{H}_{42}\) is
- A Decane
- B Dodecane
- C Eicosane
- D Hicosane
Answer & Solution
Correct Answer
(C) Eicosane
Step-by-step Solution
Detailed explanation
The given molecular formula is \(\text{C}_{20}\text{H}_{42}\).
This matches the general formula for alkanes, \(\text{C}_n\text{H}_{2n+2}\), where \(n = 20\).
The IUPAC root word for a 20-carbon chain is 'eicos'.
Therefore, the alkane with 20 carbon atoms is named eicosane.
