What’s on the Halogenoalkanes poster
SN1 against SN2, side by side.
- SN1: Two steps via a carbocation
- SN1: Rate depends on the halogenoalkane only
- SN1: Favoured by tertiary — stable carbocation
- SN1: Racemic mixture from a chiral centre
- SN2: One step, backside attack
- SN2: Rate depends on both reactants
- SN2: Favoured by primary — less steric hindrance
- SN2: Inversion of configuration
- C-I is weakest and reacts fastest; C-F is strongest and slowest. Bond enthalpy, not e…
Common nucleophiles: OH⁻ gives an alcohol, CN⁻ gives a nitrile and extends the chain, NH₃ gives an amine.

- Who is the Halogenoalkanes poster for?
- Halogenoalkanes 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 Halogenoalkanes poster?
- The C-X bond is polar, so the carbon is open to nucleophilic attack. A wall chart earns its place by being glanceable from where the work is happening, so Halogenoalkanes belongs on the wall where that physical science work actually happens, within glancing distance, rather than filed away.
- What other posters go with Halogenoalkanes?
- Alcohols, Alkanes and Alkenes sit alongside Halogenoalkanes in the Chemistry section. Printed together they make a wall rather than a single sheet, which is how a reference set actually gets used.AlcoholsAlkanesAlkenes
- Is the Halogenoalkanes poster free to download and print?
- Yes. Halogenoalkanes 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 Halogenoalkanes poster print at?
- Halogenoalkanes 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 Halogenoalkanes loses nothing.Printing guide
