Hi Chidinma! 👋 You've been studying 4 days straight — great discipline.

You're currently weak in Organic Chemistry Nomenclature (38% accuracy). Want me to quiz you on that right now, or should we build a study plan first?

Great. 10 questions, mixed difficulty, all WAEC-style. I'll explain anything you miss. Ready? 💪

Good question — and the simplest one to get a WAEC mark on. 🎯

• Alkanes have only single bonds between carbons. Think saturated. Example: methane CH₄, ethane C₂H₆.
• Alkenes have at least one double bond. Think unsaturated. Example: ethene C₂H₄.

Quick way to remember: "ane" = single, "ene" = double.

📚 This was tested in WAEC Chemistry 2021, 2022, and 2024.
