This section presents conceptually demanding and multi-step problems that test a deep understanding of the chemistry of alkanes, alkenes, and alkynes. It is designed for advanced learners who aim to master complex reaction logic, selectivity, and mechanistic reasoning.
Problems based on competing substitution, addition, and elimination reactions
Stability-based questions involving carbocations, radicals, and intermediates
Tricky regioselectivity and stereoselectivity scenarios
Structure determination from reaction outcomes
Combined problems linking hydrocarbons with isomerism and mechanisms
High-level exam and previous-year challenge problems
The problems are structured to strengthen analytical depth, enhance mechanistic clarity, and improve the ability to handle time-intensive, high-order questions.
Mastering this section ensures readiness for the toughest hydrocarbon problems encountered in competitive exams and undergraduate assessments.
Q. What is the expected product when 1-butyne undergoes hydroboration-oxidation?
A.
1-butanol
B.
2-butanol
C.
butanal
D.
butyric acid
Solution
Hydroboration-oxidation of 1-butyne leads to the formation of 2-butanol due to anti-Markovnikov addition.
