The idea
What is Alkanes, alkenes and alkynes?
Alkanes, alkenes and alkynes are the three families of hydrocarbons, molecules of only carbon and hydrogen. Alkanes have only single bonds, are saturated and fairly unreactive apart from combustion and free-radical substitution with halogens. Alkenes contain a carbon-carbon double bond whose electron-rich pi bond makes them undergo addition reactions with hydrogen, halogens, hydrogen halides and water, following Markovnikov's rule. Alkynes have a triple bond and add twice. Each family has its own naming pattern and general formula.
Where it appears: Class 10 to 12 CBSE and ICSE, GCSE and A-level, IB Chemistry, AP Chemistry, JEE and NEET.
Where learners get stuck
Why Alkanes, alkenes and alkynes is hard
Learners confuse substitution in alkanes with addition in alkenes, and misapply Markovnikov's rule when adding hydrogen halides to unsymmetrical alkenes, putting the hydrogen on the wrong carbon.
The picture a good explanation starts with: Ethane, ethene and ethyne drawn in a row with single, double and triple bonds, the pi bonds shaded, and an addition arrow showing bromine opening the double bond.
A lesson, step by step
How a lesson on Alkanes, alkenes and alkynes goes
01
Ask
Type or say "Why are alkenes more reactive than alkanes?" in your own words, in any of 26 languages.
02
Plan
The tutor plans a storyboard, one picture per idea, starting with ethane, ethene and ethyne drawn in a row with single, double and triple bonds, the pi bonds shaded, and an addition arrow showing bromine opening the double bond.
03
Explain
It explains Alkanes, alkenes and alkynes out loud while the picture builds step by step, pitched to your level (Class 10 to 12 CBSE and ICSE and up).
04
Interrupt
Say "wait, why?" or type a doubt: it stops, answers over the picture, and carries on. Ask for a different explanation any time.
05
Check
A checkpoint question makes sure the idea landed, and Test Lab keeps the practice going.
06
Your notes
Upload a PDF or a photo of your class notes or a past paper and the lesson follows your textbook's terms.
Ask it anything
Questions learners ask about Alkanes, alkenes and alkynes
- Why are alkenes more reactive than alkanes?
- What does Markovnikov's rule say about adding HBr?
- How do I name a branched alkane correctly?
Any of these, or your own, typed or spoken. The tutor answers on the picture and adapts to how well you are following.
Questions
Asked, Answered
Can LetMeTeach explain Alkanes, alkenes and alkynes?
Yes. Ask in your own words and the tutor plans a lesson on Alkanes, alkenes and alkynes: it starts with ethane, ethene and ethyne drawn in a row with single, double and triple bonds, the pi bonds shaded, and an addition arrow showing bromine opening the double bond. Then it explains each step out loud as the picture builds, stops when you say "wait, why?", and ends with a checkpoint question.
Where does Alkanes, alkenes and alkynes come up?
Class 10 to 12 CBSE and ICSE, GCSE and A-level, IB Chemistry, AP Chemistry, JEE and NEET. The lesson is pitched to your level and the exam or curriculum you follow, and you can upload your own notes or past papers so it uses your textbook's terms.
Can I learn Alkanes, alkenes and alkynes in my own language?
Yes. LetMeTeach teaches in 26 languages and plans the lesson in the language you choose rather than translating an English one, so the terms match what your textbook says. The Free plan includes 7 hours a month with no card.
