What multiplicities are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde?

1 answer:

8 0

The multiplicities that are observed for the signals in the off-resonance decoupled 13c nmr spectrum of (2e)-3-chloro acrylaldehyde is a singlet, a triplet, and a quartet. The correct option is E.

<h3>What is off-resonance decoupling?</h3>

Off-resonance decoupling is a process of removing all hydrogen and carbon coupling from a signal except for the place which is near the nucleus or joined with the nucleus.

In NMR also, the coupling of hydrogen and carbon is removed except for the place near the nucleus.

Thus, the correct option is E) a singlet, a triplet, and a quartet.

Draw the Lewis structure for methane (CH4) and ethane (C2H6) in the box below. Then predict which would have the higher boiling

Alinara [238K]

Answer:

Ethane would have a higher boiling point.

Explanation:

In this case, for the lewis structures, we have to keep in mind that all atoms must have 8 electrons (except hydrogen). Additionally, each carbon would have 4 valence electrons, with this in mind, for methane we have to put the hydrogens around the carbon, and with this structure, we will have 8 electrons for the carbon. In ethane, we will have a bond between the carbons, therefore we have to put three hydrogens around each carbon to obtain 8 electrons for each carbon.

Now, the main difference between methane and ethane is an additional carbon. In ethane, we have an additional carbon, therefore due to this additional carbon, we will have more area of interaction for ethane. If we have more area of interaction we have to give more energy to the molecule to convert from liquid to gas, so, the ethane will have a higher boiling point.

I hope it helps!
