There are three main types of chemical formulas: empirical, molecular and structural. Empirical formulas show the simplest whole-number ratio of atoms in a compound, molecular formulas show the number of each type of atom in a molecule, and structural formulas show how the atoms in a molecule are bonded to each other.

William how are you doing 4 years later?

[@wx7192]

@@aaryamangupta very good👍

[@nesw676]

Thank you for this lesson

[@Samarth_Aggarwal]

is there nothing that comes between the jump from molecular to structural formulae? like, if you consider acetic acid, you can call C2O2H4 its molecular formula, but then there's CH3COOH, which is how we usually write it and which is a bit closer to a structural formula. Do those "semi-structural formulae" not have a specific name we can refer to them with?

[@MarMaeMat]

Wow, you are easy to understand. 😍

[@rtnjo6936]

who in the world put dislikes here??) it's best explanation

[@ChotbielJKeach]

That helps!

where did the 6 come from in the molecular formula?

[@sciencenerd7639]

great video, thanks so much

Soooooooo gooooooood

[@mumunubogen2439]

Mr. Could you explain considering new chemistry students. Given C6H6, I can draw an open chain structure. Tell the new students how benzene structure was identified

Hi everyone from the year of 2024, hope you crack that chem exam ✅
