In order to determine the equivalent hydrogens in 1-chloropropane and 2-chloropropane, we need to understand the concept of hydrogen equivalence in organic compounds.
Equivalent hydrogens are hydrogens that have the same chemical environment and are indistinguishable from one another. This means that if we were to replace one of these hydrogens with a different atom or group, the resulting molecule would be identical to the original.
Let's analyze each compound separately:
1-Chloropropane:
H H H H CL
| | | | |
H-C-C-C-CL
| | | | |
H H H H
In 1-chloropropane, all the hydrogens attached to the middle carbon atom (marked with an "X") are equivalent. They have the same chemical environment because they are bonded to the same carbon atom, and there are no other atoms or groups attached to this carbon atom. Therefore, there are 3 equivalent hydrogens in 1-chloropropane.
2-Chloropropane:
H H H H
| | | | |
H-C-C-C-H
| | | | |
H H H H
In 2-chloropropane, the hydrogens on the two terminal carbon atoms (marked with an "X") are equivalent. They have the same chemical environment because they are bonded to the same carbon atom, and there are no other atoms or groups attached to these carbon atoms. Therefore, there are 2 equivalent hydrogens in 2-chloropropane.
To summarize:
- In 1-chloropropane, there are 3 equivalent hydrogens.
- In 2-chloropropane, there are 2 equivalent hydrogens.
