Which compound is an isomer of propanoic acid (CH3CH2COOH)?
arlik [135]

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>

Convert 4 x 10^-3 dL to cm^3 <br><br> Please give the work and the answer in scientific notation.
Serhud [2]

4 x  10^{-3 in dL will be 4 x  10^{-1}  cm^3

<h3>Conversion from dL to cm^3</h3>

Recall that:

Deci = 10^{-1}

Centi = 10^{-2}

Thus, 1 dl = 100 ml

This means that converting from dl to  cm^3 requires multiplying by 10^2.

Applying this principle, 4 x 10^{-3 in dL to  cm^3 will be:

4 x 10^{-3 x  10^2 cm^3 = 4 x  10^{-1}  cm^3

Therefore,  4 x 10^{-3 dl will be 4 x  10^{-1}  cm^3

Explain the optical activity of malic acid? <br>Draw a pair of stereoisomers of malic acid.​
mr_godi [17]

Under standard temperature and pressure, the optical activity of malic acid changes in the following ways:

  1. Wavelength of light
  2. Magnitude
  3. Temperature
  4. 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 C_4H_6O_5. 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:

  1. Wavelength of light
  2. Magnitude
  3. Temperature
  4. Concentration of solvent.

<h3>The stereoisomeric forms of malic acid.​</h3>

In Science, there are two (2) stereoisomeric forms of malic acid and these include:

  • L-enantiomers
  • D-enantiomers
