Identify the product obtained when 2- Chloro - 2 - methylbutane is reacted with sodium metal in presence of dry ether?
Options
- A2, 2, 3, 3 - tetramethyloctane
- B3, 3, 4, 4 - tetramethyloctane
- C2, 2, 3, 3 - tetramethylhexane
- D3, 3, 4, 4 - tetramethylhexane
Correct answer
D. 3, 3, 4, 4 - tetramethylhexane
Step-by-step solution
The given reactant is 2-chloro-2-methylbutane, which has the structure CH₃-C(Cl)(CH₃)-CH₂-CH₃ . When reacted with sodium metal in the presence of dry ether, it undergoes the Wurtz reaction. The reaction proceeds via the formation of an alkyl free radical. The cleavage of the C-Cl bond yields the radical CH₃-C^ (CH₃)-CH₂-CH₃ . Two such radicals dimerize to form the final alkane product: 2 CH₃-C(Cl)(CH₃)-CH₂-CH₃ + 2 Na CH₃-CH₂-C(CH₃)₂-C(CH₃)₂-CH₂-CH₃ + 2 NaCl The longest continuous carbon chain in the product contain
