A compound with molecular formula C ₅ H ₁₀ that gives acetone on ozonolysis is:

Step-by-step solution

Ozonolysis of an alkene cleaves the C = C double bond to form carbonyl compounds. Since one of the products is acetone, CH ₃ COCH ₃ , the original alkene must contain a ( CH ₃)₂ C = group. The molecular formula of the compound is C ₅ H ₁₀ . Subtracting the 3 carbon atoms of the acetone fragment leaves 2 carbon atoms for the other fragment, which must be an ethylidene group, = CHCH ₃ . Combining these two fragments, the structure of the alkene is ( CH ₃)₂ C = CHCH ₃ , which is 2-methyl-2-butene. The ozonolysis react
