What would be the whole name of 2-butene and hydroiodic acid. Or the diagram.

Any help would be greatly appreciated.

As I suggested two days ago, you add it across the double bond. That is, break the double bond so you have a single bond to single bond C, then to the left C place the H from HI and to the right C place the I so you will have CH3CH2CHICH3. I would then name that compound as 2-iodobutane.

h---c--C====c---c---h

This is 2-butene where do I insert the HI for hydroiodic aci?

The whole name of 2-butene combined with hydroiodic acid would be 2-iodobutane.

Here is the structural diagram of 2-butene:

And here is the structural diagram of hydroiodic acid:

To determine the full name of 2-butene when reacted with hydroiodic acid, we first need to understand the structure of both compounds.

2-butene is an alkene, which means it contains a carbon-carbon double bond. It has a total of four carbon atoms and eight hydrogen atoms in its structure. The double bond is located between the second and third carbon atoms. The complete structure can be represented as follows:

CH3CH=CHCH3

Hydroiodic acid, on the other hand, is a binary acid composed of hydrogen (H) and iodine (I). Its chemical formula is HI.

When these two compounds react, the double bond in 2-butene breaks and the hydrogen (H) of hydroiodic acid adds to one of the carbon atoms, resulting in the formation of a new compound called 2-iodobutane. The chemical equation for the reaction can be written as follows:

CH3CH=CHCH3 + HI → CH3CHICH2CH3

Therefore, the full name of the product is 2-iodobutane.
