When 2-bromo-3-methylbutane is heated with alcoholic KOH, it gives a major product A. Product A is then subjected to ozonolysis with O ₃ followed by boiling H ₂ O . The final organic products formed are:

Step-by-step solution

The starting material is 2-bromo-3-methylbutane: CH ₃- CH ( Br )- CH ( CH ₃)- CH ₃ . Heating with alcoholic KOH causes dehydrohalogenation (an elimination reaction). According to Zaitsev's rule, the more substituted alkene is formed as the major product. Elimination of HBr yields 2-methylbut-2-ene as the major product A: CH ₃- C ( CH ₃)= CH - CH ₃ Product A is then reacted with O ₃ followed by boiling H ₂ O . The absence of a reducing agent (like Zn or dimethyl sulfide) means this is an oxidative ozonolysis. During
