Halogen compounds — practice question

Sodium methoxide, $\text{Na}^+\text{CH}_3\text{O}^-$, undergoes nucleophilic substitution with 2-chloro-2-methylpropane. The nucleophile is the $\text{CH}_3\text{O}^-$ ion. Which row is correct?

  • Aintermediate or transition state: $(\text{CH}_3)_3\text{C}^+$; product: $(\text{CH}_3)_3\text{COCH}_3$
  • Bintermediate or transition state: $(\text{CH}_3)_3\text{C}^+$; product: $(\text{CH}_3)_3\text{CCH}_2\text{OH}$
  • Cintermediate or transition state: $[\text{HOCH}_2\cdots\text{C}(\text{CH}_3)_3\cdots\text{Cl}]^-$; product: $\text{HOCH}_2\text{C}(\text{CH}_3)_3$
  • Dintermediate or transition state: $[\text{H}_3\text{CO}\cdots\text{C}(\text{CH}_3)_3\cdots\text{Cl}]$; product: $\text{H}_3\text{COC}(\text{CH}_3)_3$
