Give the name of the product from complete hydrogenation of each of the following:
2-ethyl-1-hexene
2-ethylhexane
2-ethylhexane
To determine the product from the complete hydrogenation of 2-ethyl-1-hexene, we first need to understand the process of hydrogenation and the structure of 2-ethyl-1-hexene.
Hydrogenation is a chemical reaction in which hydrogen gas (H2) is added to an unsaturated compound, typically an alkene or alkyne, to form a saturated compound. This reaction is commonly used in various industries, including the production of oils, fats, and plastics.
Now, let's look at the specific compound, 2-ethyl-1-hexene. The structure of 2-ethyl-1-hexene can be represented as follows:
CH3CH2CH(CH3)CH2CH=CH2
To perform complete hydrogenation, all the double bonds (C=C) present in the molecule need to be converted into single bonds (C-C) by adding hydrogen gas.
During hydrogenation, each double bond will undergo an addition reaction with a molecule of hydrogen gas (H2), resulting in the formation of a saturated compound. In this case, 2-ethyl-1-hexene contains only one double bond, so only one hydrogen molecule will be added.
After complete hydrogenation, the double bond is replaced with a single bond, resulting in the addition of two hydrogen atoms. Therefore, the product of the complete hydrogenation of 2-ethyl-1-hexene will be:
CH3CH2CH(CH3)CH2CH2CH3
The product is 2-ethylhexane.
By understanding the structure of the compound and the concept of hydrogenation, you can determine the product of the complete hydrogenation process.
