Which is the correct lewis structure for ethylene, c2h4?
1 answer:
Remember this, when trying to find a valid lewis structure, every single atom must have a total of 8 shared electrons (full octet). Since I only have 4 hydrogens to work with, two on each carbon, I assumed a double bond in the middle. This way, every atom has a full octet, except for hydrogen which is most stable with just two electrons. If there were just a single bond in between the carbons, each carbon would only have a total of 6 shared electrons which violates the octet rule. So a double bond is a must. This is ethylene by the way.

The correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.
<h3>IUPAC NAME:</h3>It is systematic way of nomenclature of organic compounds.
It is based on the position of functional groups, preference of the functional group, long or short chain of carbon, preference of double bond, single and triple bond, branching of carbon chain, etc.
The given compound is 1,1,1-trimethylheptane.
The given name is wrong according to IUPAC name because the numbering of carbon atom should be done in that way in which the carbon atom chain is largest.
Here, in this case the numbering is done from right side. Thus the largest carbon chain have 8 carbon atom.
If the numbering is done according to the question, number of carbon atom in straight chain is 7.
Thus, we concluded that the Correct IUPAC name of 1,1,1-trimethylheptane is 2,2-dimethyloctane.
