Answer:
D) HCOOCH2CH3
Explanation:
An isomer of a compound is defined as a chemical substances with the same formula (That is, same atoms) but in different structures.
For propanoic acid, there are <em>3 atoms of C, 6 atoms of H and 2 atoms of oxygen.</em>
A) CH2CHCOOH
. Here you have 3 atoms of C but 4 atoms of H. That means this compound is not an isomer.
B) CH3CH2CH2COOH
. Here, there are 4 atoms of C. Thus, is not an isomer.
C) CH3CH(OH)CH2OH. This structure has 3 atoms of C, but 8 atoms of H. Thus, is not an isomer.
D) HCOOCH2CH3. Here, there are 3 atoms of C, 6 atoms of H and 2 atoms of O. Thus, this structure <em>is an isomer of propanoic acid.</em>

4 x
in dL will be 4 x
<h3>Conversion from dL to cm^3</h3>
Recall that:
Deci = 
Centi = 
Thus, 1 dl = 100 ml
This means that converting from dl to
requires multiplying by
.
Applying this principle, 4 x
in dL to
will be:
4 x
x
= 4 x
Therefore, 4 x
dl will be 4 x

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
<h3>What is an optical activity?</h3>
An optical activity is also referred to as optical rotation and it can be defined as the ability of a substance or chemical compound to rotate the plane of polarization of a beam of plane-polarized light that passes through it.
<h3>What is malic acid?</h3>
Malic acid refers to an organic compound (dicarboxylic acid) that is typically made by all living organisms and its molecular formula is
. Malic acid is considered to be one of the most satisfactory substances to be used when studying optical activity because of its chemical properties such as having single asymmetric carbon atoms.
Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:
- Wavelength of light
- Magnitude
- Temperature
- Concentration of solvent.
