Which structure defines the hydroxyl functional group?(1 point)
options:
CH3
NH 2
OH
SH
OH
The structure that defines the hydroxyl functional group is OH.
The structure that defines the hydroxyl functional group is OH.
To determine this, let's break down each option:
- CH3 represents the methyl functional group, which consists of a carbon atom bonded to three hydrogen atoms. It does not contain an oxygen atom, which is necessary for the hydroxyl functional group.
- NH2 represents the amino functional group, which consists of a nitrogen atom bonded to two hydrogen atoms. Again, it does not contain an oxygen atom, so it does not define the hydroxyl functional group.
- OH represents the hydroxyl functional group. It consists of an oxygen atom bonded to a hydrogen atom. This structure is characterized by the presence of an oxygen atom bonded directly to a hydrogen atom, making it the correct option for the hydroxyl functional group.
- SH represents the thiol functional group, which consists of a sulfur atom bonded to a hydrogen atom. Like the other options, it lacks the presence of an oxygen atom, so it does not define the hydroxyl functional group.
Therefore, the correct option that defines the hydroxyl functional group is OH.
