Why symmetrical molecules have higher bioling points than unsymmetrical molecules?
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.

Why is the boiling point for ch3ch2ch2ch2oh higher than the boiling point for ch3ch2ch2ch2sh?
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.
Is the concentration of water molecules higher in pure water or in sugar water?
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.
Do molecules collide more frequently in higher temperatures?
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.
Does longer hydrocarbon molecules have higher boiling points than short hydrocarbon molecules?
yes
What is the connection between the size of the molecules in crude oil and their condensing or boiling point's?
Smaller molecules have a lower boiling point, and larger molecules have a higher boiling point. Source: Learnt this in class today.
Why are symmetrical faults more severe than unsymmetrical faults?
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.

Why is the bioling point of hexane greater than that of pentane?
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.
Why do polar and nonpolar molecules have different properties?
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.

What is the dictionary explanation of lopsided?
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.
Is kinetic energy higher in larger molecules?
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.
Is the concentration of water molecules higher in pure water or in sugar water?
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.
Why amplitude modulation is called as collector modulation?
amplitude modulation using collector modulator gives:More symmetrical envelope• Higher power efficiency• Higher output power• Need higher amplitude modulatingsignal
Do molecules collide more frequently in higher temperatures?
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.
What is affected by the mass of molecules that make up the material and the distance between them?
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.
Why does it get colder at higher altitudes?
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.
Do molecules at lower temperatures move more quickly than those at higher temperature?
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.
