Consider the series of reactions given and identify the final product [Z].

Correct answer

3

Step-by-step solution

The starting material is 2-methylpropan-2-ol. Treatment with 20% H₃PO₄ causes acid-catalyzed dehydration to form 2-methylpropene [W]. (CH₃)₃C-OH H^+ (CH₃)₂C=CH₂ Next, 2-methylpropene [W] undergoes hydroboration-oxidation with (BH₃)₂ in THF followed by H₂O₂ / NaOH . This results in the anti-Markovnikov addition of water, yielding the primary alcohol 2-methylpropan-1-ol [X]. (CH₃)₂C=CH₂ (i) (BH₃)₂, (ii) H₂O₂/OH^- (CH₃)₂CH-CH₂-OH Oxidation of the primary alcohol 2-methylpropan-1-ol [X] with CrO₃ yields the correspondi
