Select all the correct answers. which compounds have the empirical formula ch2o? a. c2h4o2 b. c3h6o3 c. ch2o2 d. c5h10o5 e. c6h12o6

Compounds having the same empirical formula are:

Explanation:

Empirical formula tells us about the proportion of the elements present in the compound but it do not tells us about the actual numbers of atoms of the elements present in the compound.

In given empirical formula that is proportion of  C:H:O = 1:2:1

In the proportion of C:H:O =2:4:2= 1:2:1

In the proportion of C:H:O =3:6:3= 1:2:1

In the proportion of C:H:O =1:2:2= 1:2:2

In the proportion of C:H:O =5:10:5= 1:2:1

In the proportion of C:H:O =6:12:6= 1:2:1

Compounds having the given empirical formula are:

The chemical compounds that have the empirical formula are:

A.C2H4O2

B.C3H6O3

D.C5H10O5

E.C6H12O6

An empirical formula can be defined as a formula that gives the smallest and simplest whole number ratio of the atoms of a chemical element found in a chemical compound.

The simplest whole number ratio of the atoms of   is:

= 1:2:1

For :

= 2:4:2 = 1:2:1

For :

= 3:6:3 = 1:2:1.

For :

= 1:2:2 = 1:1:1  (Incorrect)

For :

= 5:10:5 = 1:2:1

For :

= 6:12:6 = 1:2:1
