Question

In the presence of platinum catalyst, hydrocarbon A adds hydrogen to form n-hexane. When hydrogen bromide is added to A instead of hydrogen, only a single bromo compound is formed. Which of the following is A?
(a) CH₃ — CH₂ — CH = CH — CH₂ — CH₃
(b) CH₃ — CH₂ — CH₂ — CH = CH — CH₃
(c) CH₃ — CH = CH — CH₂ — CH₂ — CH₃
(d) CH₂ = CH—CH₂—CH₂—CH₂—CH₃

Answer 1

CH₃ — CH₂ — CH₂ — CH = CH — CH₃
