The addition of free ions to water increases its boiling point (and decreases its melting point). Sulfuric acid contains two types of ions: H+ (or more accurately H3O+) and HSO4-. However, there is nothing special about sulfuric acid in this regard. If you have the same concentration of a solution of salt water (NaCl) or many other ionic compounds, the boiling point would be the same. The nature of the ions doesn't matter, just how many are in the solution.
The much larger iodine atoms in HI former stronger van der Waals bonds to adjacent molecules than do the chlorine atoms in HCl. More energy is required to break the bonds in HI, so that the boiling point is higher.
Hydrogen bonds occur when the hydrogen atoms are positively charged because they attract neighbouring electrons.This means the hydrogen atom is shared between 2 molecules which means there is a larger intermolecular force. Although covalent bonds are stronger than hydrogen bonds, the large intermolecular force in the compound requires more energy to break apart so it has a higher melting and boiling point.
Hope I didn't cofuse you!
Water is a polar molecule.
It is made of two Hydrogen atoms and an Oxygen atoms. Oxygen is a more electronegative atom, (i.e. It has a stronger attraction for electrons) thus it tends to pull electrons away from the hydrogens. This means the electrons spend more time around the Oxygen atom, giving it a slight negative charge, while the Hydrogens are left with a slight positive charge. Because unlike electrical charges attract, one molecule of water is attracted to another (i.e. The positive hydrogen of one H2O molecule is attracted to the negative oxygen atom of another H2O molecule) forming a hydrogen bond. Because of this bond it takes more heat energy to overcome these bonds and turn the liquid of H2O into a gas.

The difference in electronegativity between H an F is greater than that between H and Cl. As a result HF is more polar than HCl. As a result intermolecular attraction is greater.
Because the bonds between the atoms in water are stronger than in hydrogen sulfide.

Because of the hydrogen bonds in HCl and it's polarity. High polarity = high boiling point. All alkanes (methane) are nonpolar and have low boiling points. Alcohols and compounds with hydrogen bonding have higher boiling points because hydrogen bonds are very strong. Ask a chemistry teacher if you need a better explanation.
Due to large number of hydrogen bonds viscosity and boiling points of sulphuric acid are high
because it does not have a high boiling point.
The boiling point increase at high pressure.
K2S will have high boiling point than CH3Cl.

The boiling point of metalloids is not so high.
high boiling point low melting point
Chromium has a high boiling point as opposed to nonmetals. Metals tend to have high boiling points.
No, 68 is a low boiling point.
because it does not have a high boiling point.
Boiling point is a property not a force; but a high boiling point indicate a strong intermolecular force.
The boiling point increase at high pressure.
K2S will have high boiling point than CH3Cl.
No. Fluorine has a very low boiling point
They Have a low boiling point
