Which molecule has the strongest intermolecular forces?
A. HOCH2CH2CH2OH
B. CH3CH2CH2OH
C. CH3CH2CH2CH3
D. HOCH2CHOHCHOHCH2OH
I'm pretty sure it's C.
HOCH2CHOHCHOHCH2 THATS THE ANSWER
JUST TOOK THE TEST ON APEX
Consider the number of OH bonds dangling off of molecule D. https://www.masterorganicchemistry.com/2010/10/01/how-intermolecular-forces-affect-boiling-points/
But why is that D oml apex sucks
Well, let me play the devil's advocate here, because I'm a clown bot and I love a good debate. While C might seem like the right answer because it has more atoms, it's actually not the molecule with the strongest intermolecular forces. *cue suspenseful music* The correct answer is D! HOCH2CHOHCHOHCH2OH.
Why, you ask? Well, it's all about the power of hydrogen bonding, my friend. Molecule D has more hydroxyl groups (OH) than the other options, meaning it has more opportunities for hydrogen bonding. And you know what they say, the more, the merrier!
So, while C might seem like it has the advantage, it's actually D that takes the crown for the molecule with the strongest intermolecular forces. It's always the quiet ones you have to watch out for, right?
To determine which molecule has the strongest intermolecular forces, we need to consider the types of intermolecular forces present in each molecule. Intermolecular forces include dipole-dipole forces, hydrogen bonding, and London dispersion forces.
In option A (HOCH2CH2CH2OH), we have a molecule with one hydroxyl (-OH) group. This molecule can form hydrogen bonds due to the presence of the highly electronegative oxygen atom and hydrogen bonding is a strong intermolecular force.
In option B (CH3CH2CH2OH), we have a molecule with one hydroxyl (-OH) group, similar to option A. So, it can also form hydrogen bonds.
In option C (CH3CH2CH2CH3), we have a straight-chain alkane molecule without any functional groups that can participate in hydrogen bonding. However, it can exhibit London dispersion forces, which are relatively weaker compared to hydrogen bonding.
In option D (HOCH2CHOHCHOHCH2OH), we have a molecule with multiple hydroxyl (-OH) groups. The presence of multiple hydroxyl groups increases the likelihood of forming hydrogen bonds compared to option A and B.
So, between the given options, D (HOCH2CHOHCHOHCH2OH) has the strongest intermolecular forces due to the multiple hydroxyl groups, which allows for more hydrogen bonding potential.
