Which structure correctly represents the bonding in a hydrocarbon molecule?

a.
6 carbon atoms forming single bonds with 13 hydrogen atoms; the second carbon from the right has a methyl group attached to it
b.
8 carbon atoms forming single bonds with 18 hydrogen atoms; a triple bond exists between the third and fourth carbon atom from the right
c.
four carbon atoms forming single bonds with seven hydrogen atoms; a methyl group forms a single bond with the second carbon from the left
d.
three carbon atoms forming single bonds with seven hydrogen atoms with; a double bond exists between the first and second carbon atom from the right

A.  6 carbon atoms forming single bonds with 13 hydrogen atoms the second carbon from the right has a methyl group attached to it.

Explanation:

Here 6 carbon atoms forming single bonds with 13 hydrogen atoms the second carbon from the right has a methyl group attached to it,has a chemical formula of .

It is in the form of ,Which is the general formula for alkanes.

So here,the formula is ,which is the general formula of Heptane.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.
