Question

multiple choice 1 point when hydroxyl groups are added to a hydrocarbon chain, which of the following is true? non - polar covalent bonds are formed making the molecule more hydrophilic polar covalent bonds are formed making the molecule more hydrophilic non - polar covalent bonds are formed making the molecule more hydrophobic polar covalent bonds are formed making the molecule more hydrophobic

Explanation:

Hydroxyl groups (-OH) have oxygen, which is highly electronegative, creating polar covalent bonds between O and H, and between the hydroxyl group and the hydrocarbon chain. Polar groups interact favorably with water, increasing the molecule's hydrophilicity (water-attracting nature), unlike nonpolar hydrocarbon chains which are hydrophobic.

Answer:

Polar covalent bonds are formed making the molecule more hydrophilic
