Correct IUPAC naming of the given compound is:
Correct IUPAC naming of the given compound is:
- A. pent-3-ene
- B. 2, 2-diethylethene
- C. hexene
- D. 2-ethylbutene
Step-by-step solution
The compound (CH3CH2)2C=CH2 (often mistakenly called 2,2-diethylethene) has a four-carbon chain with a double bond; the correct IUPAC name is 2-ethylbut-1-ene. Among the options, '2-ethylbutene' (D) is the closest, as it correctly identifies the parent chain and substituent, though it omits the double bond locant. Options A, B, and C are incorrect: A 'pent-3-ene' would be a five-carbon chain, B '2,2-diethylethene' is a non-IUPAC name, and C 'hexene' is too vague.
