What’s on the Alkenes poster
A 5-row table: Reagent · Product · Conditions.
Electrophilic addition reactions, general formula CₙH₂ₙ.
- H₂ — Alkane — Ni catalyst, 150°C
- Br₂ — Dibromoalkane — Room temperature — decolourises
- HBr — Halogenoalkane — Room temperature
- H₂O — Alcohol — Steam, H₃PO₄, high pressure
- KMnO₄ — Diol — Cold, dilute, acidified
Markovnikov's rule: with an unsymmetrical alkene and HX, the hydrogen adds to the carbon already carrying more hydrogens.

- What’s on the Alkenes poster?
- A 5-row table: Reagent · Product · Conditions. Electrophilic addition reactions, general formula CₙH₂ₙ.

- Who is the Alkenes poster for?
- Alkenes belongs to the Chemistry section rather than to a school year, because physical science is not something one grade owns. Anyone learning organic can pin it up — a beginner, a student mid-course, or someone revising years later.
- When should you use the Alkenes poster?
- The pi bond is electron-rich, so alkenes attract electrophiles. A wall chart earns its place by being glanceable from where the work is happening, so Alkenes belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Alkenes?
- Alcohols, Alkanes and Benzene sit alongside Alkenes in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AlcoholsAlkanesBenzene
- Is the Alkenes poster free to download and print?
- Yes. Alkenes downloads as a free PDF with no account, no email and no watermark, like everything else in the Chemistry section. Print as many copies as you like for a home, a classroom, a library or a tutoring group; reselling the file is the only thing the licence rules out.Read the licence
- What size does the Alkenes poster print at?
- Alkenes is a vector PDF laid out for US Letter, and prints on A4 with Fit to page — the same file, no separate download. Because every mark on it is drawn rather than photographed, it stays sharp enlarged to A3, A2 or A1 at a copy shop. Colour carries emphasis only, so a greyscale print of Alkenes loses nothing.Printing guide
