what are the condensed structured formulas of the products in each of the following reactions:

cyclohexane+ H2-->Pt

and
cis-2-butene+ H2 -->Pt

I can't find anything definite about the first reaction. The second one forms butane.

There is no reaction in the first reaction. It is not possible to reduce cyclohexane further.

And agreed, the second one forms butane.

To determine the condensed structured formulas of the products in each reaction, we first need to understand the reactions themselves.

1. Cyclohexane + H2 --> Pt:
This reaction is an example of hydrogenation, where hydrogen gas (H2) is added to cyclohexane (C6H12) in the presence of a catalyst such as platinum (Pt).

During hydrogenation, the double bonds in the cyclohexane molecule are broken and replaced by single bonds with hydrogen atoms. This converts cyclohexane into cyclohexane saturated with hydrogen, which is known as cyclohexane. Thus, the product of this reaction is simply cyclohexane itself.

The condensed structured formula of cyclohexane is: C6H12.

2. cis-2-butene + H2 --> Pt:
In this reaction, cis-2-butene (C4H8) undergoes hydrogenation with hydrogen gas (H2) in the presence of a platinum (Pt) catalyst.

Similar to the previous reaction, the double bond in the cis-2-butene molecule is broken and replaced with a single bond with a hydrogen atom. As a result, cis-2-butene is converted into a saturated molecule known as butane.

The condensed structured formula of butane is: C4H10.

Therefore, the product of the reaction between cis-2-butene and H2 is butane (C4H10).

In summary:
1. Cyclohexane + H2 --> Pt:
Product: Cyclohexane (C6H12).

2. cis-2-butene + H2 --> Pt:
Product: Butane (C4H10).
