3D molecules

3D molecules for JEE and NEET chemistry you can turn in your hand.

669 molecules from JEE and NEET chemistry turn in 3D inside Niera's answers. Ask about a shape, an isomer or a mechanism, and the molecule is drawn where you are reading. It is free while it is in beta.

Nitrobenzene turned in 3D over a step of the nitration of benzene, drawn inside an answer

It is 1 a.m. The book draws XeF4 flat on the page, and the question asks where the lone pairs sit.

Turn it and look.

Mechanisms you can step through.

A mechanism in an answer is drawn as steps you can scrub back and forth, arrows included. In the nitration here, you can stop at the arenium ion and see the carbon that has gone sp3, which is why the ring is no longer aromatic.

The nitration of benzene drawn step by step inside an answer, stopped at the arenium ion, with a bar to move between the steps

Shapes from VSEPR.

The molecular shapes lab builds 63 species from their electron pairs, so you can see where each lone pair sits and why the bond angles close up around it. Any molecule an answer names opens in 3D from that answer.

  • ShapesFrom BeCl2 and BF3 to SF4, ClF3, XeF4 and XeF6.
  • PolarityWater, ammonia, chloroform and sulphur dioxide side by side, to show which carry a dipole and why.
  • Any phoneDrawn without 3D graphics hardware, so they turn smoothly on an ordinary Android phone.

Questions people ask

01Which molecules are there?

669, chosen from the chemistry that JEE and NEET questions use: organic compounds, inorganic species and the ions in between.

02Do I need to install anything?

No. The molecules run in the browser, on a phone or a laptop.

03Can I see them without asking a question?

The shapes and polarity labs open from the Library, and any molecule an answer names can be opened from that answer.

04What does it cost?

Nothing while it is in beta, and no card is asked for. Join the waitlist and your invitation arrives by email when a seat opens.

Don't memorise the shape. Turn it.
