They don't - quite the opposite!
Boiling point depends on the strength of intermolecular forces and on the molecular weight of the molecule.
One factor contributing to intermolecular forces is an asymmetrical distribution of electric charge - in this case, the dipole charges of adjacent molecules can orient towards each other and allow for increased bonding strength. Conversely, in a symmetrical molecule this cannot occur, so the bonds will be weaker. This means that all other factors being equal, an symmetrical molecule will have weaker intermolecular bonds and thus a lower boiling point.
For example, a symmetric methane molecule (weight ~16) boils at a lower temperature than the less-symmetric ammonia (NH3, weight ~17), which in boils at a lower temperature than the very asymmetric water (H2O, weight ~18) depite the fact that their weights are nearly identical.
Conversely, a very highly symmetric radon gas atom remains a gas at room temperature despite a weight of 222 g/mol.
The CH3CH2CH2CH2OH molecules can form strong hydrogen bonds with each other due to the presence of the lone pairs of electrons on O and the H atom which is bonded to the O atom, while CH3CH2CH2CH2SH molecules are unable to due to the absence of H atoms bonded to either F, O or N atoms. As such, more heat energy is required to overcome the stronger hydrogen bonds and thus CH3CH2CH2CH2OH has a higher bioling point.
The concentration of water molecules is higher in pure water compared to sugar water. Sugar water has sugar molecules dissolved in it, which decreases the concentration of water molecules relative to pure water.
Yes, molecules collide more frequently in higher temperatures because they move faster and have higher kinetic energy. This increased speed and energy lead to more frequent collisions between molecules.
yes
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
In power engineering, specifically three-phase power, a symmetric, symmetrical or balanced fault is a fault which affects each of the three-phases equally.In power engineering, specifically three phase power, an asymmetricor unbalanced fault is a fault which does not affect each of the three phases equally.for these reasons thus symmetrical faults are more severe than the former.

The boiling point of hexane is higher than that of pentane because hexane has a larger molecular mass and stronger London dispersion forces between its molecules. These stronger intermolecular forces require more energy to overcome, resulting in a higher boiling point for hexane compared to pentane.
Polar molecules have an uneven distribution of charge due to the presence of polar covalent bonds, leading to interactions like hydrogen bonding and higher boiling points. Nonpolar molecules have a more symmetrical distribution of charge, making them less interactive with other molecules and typically having lower boiling points.

Lopsided' means "heavier, larger, or higher on one side than on the other." It also can indicate "sagging on one side." Synonyms include: uneven, unsymmetrical, and unbalanced.
Kinetic energy is directly related to the speed of molecules, not their size. In general, larger molecules tend to have higher potential energy due to their higher mass, which can result in higher kinetic energy when they are moving.
The concentration of water molecules is higher in pure water compared to sugar water. Sugar water has sugar molecules dissolved in it, which decreases the concentration of water molecules relative to pure water.
amplitude modulation using collector modulator gives:More symmetrical envelope• Higher power efficiency• Higher output power• Need higher amplitude modulatingsignal
Yes, molecules collide more frequently in higher temperatures because they move faster and have higher kinetic energy. This increased speed and energy lead to more frequent collisions between molecules.
The density of the material is affected by the mass of molecules and the distance between them. If the molecules have higher mass and are closer together, the material will have higher density.
At higher altitudes, the air pressure decreases, causing the air molecules to spread out more. This spreading out of molecules leads to a decrease in temperature, making it colder at higher altitudes.
No, molecules at higher temperatures move more quickly than those at lower temperatures. Higher temperatures provide molecules with more kinetic energy, causing them to move faster.
