Which functional group is nonpolar?(1 point)
Responses
sulfhydryl
carbonyl
hydroxyl
methyl
The methyl group is nonpolar. It consists of a carbon atom attached to three hydrogen atoms (-CH3). This arrangement does not have a significant difference in electronegativity between the carbon and hydrogen atoms, which means that electrons are shared relatively equally and there is no significant dipole moment. As a result, the methyl group does not have a charge and is considered nonpolar.
what is the correct answer
The correct answer is:
methyl
The methyl group (-CH3) is the nonpolar functional group among the options provided.
To determine which functional group is nonpolar, we need to understand the characteristics of each group. Let's go through each option:
1. Sulfhydryl: The sulfhydryl group (-SH) consists of a sulfur atom bonded to a hydrogen atom. This group is typically polar because the sulfur atom tends to be more electronegative than hydrogen, resulting in an uneven distribution of electron density.
2. Carbonyl: The carbonyl group (C=O) consists of a carbon atom double-bonded to an oxygen atom. This group is typically polar because oxygen is more electronegative than carbon, creating partial positive (carbon) and partial negative (oxygen) charges.
3. Hydroxyl: The hydroxyl group (-OH) consists of an oxygen atom single-bonded to a hydrogen atom. This group is polar because oxygen is more electronegative than hydrogen, resulting in a partial negative charge on the oxygen and a partial positive charge on the hydrogen.
4. Methyl: The methyl group (-CH3) consists of a carbon atom bonded to three hydrogen atoms. This group is nonpolar because carbon and hydrogen have similar electronegativities, which leads to an even distribution of electron density.
Therefore, the nonpolar functional group among the options provided is the methyl group.
