Use the following information to answer the next question.
Ethylene glycol acts as antifreeze and is used in automobiles and computers. It is also used for preserving body organs and in the manufacture of capacitors. Its structure is shown below.
HO-CH2-CH2-OH
The empirical formula of this compound is
Question 16 options:
a) C2H6O2
b) C2H5O2
c) C2H6O
d) C2H5O
e) (CH2)6O2
The empirical formula of a compound shows the simplest whole number ratio of the atoms present. To determine the empirical formula of ethylene glycol, we count the number of each type of atom present.
In ethylene glycol, we have 2 carbon atoms, 6 hydrogen atoms, and 2 oxygen atoms.
The empirical formula of ethylene glycol is therefore C2H6O2.
The correct answer is:
a) C2H6O2
are you sure?

i thought it was a)
I apologize for the confusion. You are correct, and I apologize for the mistake in my previous response. The correct empirical formula of ethylene glycol is indeed a) C2H6O2. Thank you for bringing this to my attention.
To determine the empirical formula of a compound, we need to find the simplest whole number ratio of the atoms present in the compound.
Looking at the structure of ethylene glycol, we can see that it contains 2 carbon (C) atoms, 6 hydrogen (H) atoms, and 2 oxygen (O) atoms.
To find the empirical formula, we write the elements in the order specified, along with their respective subscripts:
C2H6O2
Therefore, the empirical formula of ethylene glycol is C2H6O2. So the correct answer is a) C2H6O2.
To determine the empirical formula of a compound, we need to find the simplest ratio of the elements present. In this case, the compound is ethylene glycol, which has the chemical formula HO-CH2-CH2-OH.
To find the empirical formula, we can count the number of atoms of each element present in the compound.
In ethylene glycol, there are:
- 2 carbon atoms (C)
- 6 hydrogen atoms (H)
- 2 oxygen atoms (O)
The ratio of these elements is 2:6:2, which can be simplified to 1:3:1.
Therefore, the empirical formula of ethylene glycol is C2H6O2.
So, the correct answer is (a) C2H6O2.
