A student states that this structural formula represents a hydrocarbon.
DedPeter [7]
Answer: <span>Yes, a hydrocarbon is any compound that contains hydrogen and oxygen.

Justification:

First, I will try to rewrite the given structural formula since it is misrepresented.

This should be the right structural formula:

       H    H
       |      |
H - C  -  C - OH
       |      |
      H     H

And, yes the definition of hydrocarbon is that it is most simple organic compound constitured only by atoms of carbon (C) and hydrogen (H).

By the way, that hydrocarbon is also represented as CH3 - CH2 OH, it is an alcohol (since it has the functional group OH) and its name is ethanol.

ArbitrLikvidat [17]
For this case, Only 1 isotope would be present, i.e. the principal element with mass M=13 and then one isotope at mass M+2. <span>We are assuming that the principal element is the one that is the lowest mass - by definition, an isotope is one where there are additional neutrons - hence the mass increases, but the proton count is the same.

Brums [2.3K]

Answer:

Sorry; I am unfamiliar with the details they taught you. I would guess #3, for it allows kinetics to “work on the particles”. #1 makes no sense; what is

“Large”? #2 infers all particles are charged....#4. Seems unclear to me.

Maybe these thoughts will jar your memory.
