Question

Sort the molecular compounds in the table into groups with the same empirical chemical formula.That is, select group one next to all the components with the first empirical formula.(If all four compounds have the same empirical formula, then they all end up in group one)Next, select group to next to all the components with a second empirical formula and so on.It’s all for compounds Have different empirical formulas, and then they’ll Each end up alone in their own group: Compound a will have a alone group 1 compound be will have alone group 2 and so on.About sketches, the line stand for chemical bonds between the atoms. Just ignore the dots. They stand for lone pairs and you’ll learn more about them later. You do not need to know anything about lone pairs to solve a problem. (See picture to solve the problem)

Answer 1

Empirical Formula: a formula giving the proportions of the elements present in a compound but not the actual numbers or arrangement of atoms.

-------------------------------------------------------------------------------------------------

A) We call Group 1:

C3H6O3 => simplifying: CH2O

B) C4H4O2 => simplifying: C2H2O

Its empirical formula is different from A, so we call it Group 2.

C) C2H2O2 =>simplifying: CHO

It is different from the 2 before. We call it Group 3.

D) C5H10O5 => simplifying: CH2O

Look at A, these two have the same empirical formula. We put D in Group 1

First, I changed the developed formulas into molecular formulas, then I simplified the subindexes and I got the empirical formulas. After that, I compared every empirical formula.
