∙ 11y agoHydrogen bonding will only occur between hydrogens connected to electronegative atoms (N, O, F) and molecules with other electronegative atoms. The proton in an aldehyde group is attached to a carbonyl (C=O), which isn't sufficiently electron withdrawing to create the dipole necessary for hydrogen bonding.

∙ 11y agoHydrogen bonding requires a hydrogen atom bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) to interact with another electronegative atom. In aldehydes and ketones, the hydrogen atoms attached to the carbonyl group are not sufficiently electronegative to form hydrogen bonds, so hydrogen bonding does not occur between molecules of aldehydes and ketones.
Hydrogen bonding in water molecules exists due to the large electronegativity difference between hydrogen and oxygen, allowing a strong dipole-dipole interaction. Hydrogen sulfide lacks this strong electronegativity difference between hydrogen and sulfur, resulting in weaker van der Waals forces instead of hydrogen bonding.
Aldehydes and ketones have lower boiling points than their corresponding alcohols because aldehydes and ketones have weaker intermolecular hydrogen bonding due to the absence of -OH groups. The presence of -OH groups in alcohols allows for stronger hydrogen bonding between molecules, leading to higher boiling points.
No, hydrogen bonds are not formed between benzene molecules.
Hydrogen bonding is strongest in molecules of H2O (water) because oxygen is highly electronegative, creating a large difference in electronegativity between the hydrogen and oxygen atoms which strengthens the hydrogen bonding.
Cohesion is not directly attributable to hydrogen bonding between water molecules. Cohesion is the property of water molecules being attracted to each other due to hydrogen bonding, but it does not solely depend on hydrogen bonding for its existence.

Bonding between water molecules is referred to as hydrogen bonds.
Hydrogen bonding enables water molecules to bond to each other.
The hydrogen bonding present between the two molecules is known as intermolecular hydrogen bonding, the molecules may be similar or may be dissimilar. The molecules having intermolecular hydrogen bonding have high melting and boiling points and low volatility. They are more soluble in water as compared to the molecules having intramolecular hydrogen bonding.
A surfactant.
No, hydrogen bonds are not formed between benzene molecules.
Within the molecule itself, water exhibits ionic bonding. Between the water molecules, there is hydrogen bonding.
Hydrogen bonding is a type of intermolecular force of attractionAdded:This is between molecules.It is not as strong as chemical bonding within molecules (intramolecular) though.
The molecules of water are held together by hydrogen bonding between molecules.These are electrostatic bonds (attraction forces between opposite charges) that hydrogen makes with the oxygen of neighbouring molecules. Hydrogen, when bonded to oxygen to form water molecules, is slightly positive and the oxygen in the water molecule is slightly negative. Hydrogen gets attracted to the neighbouring slightly negative oxygen atoms.This is great for life on Earth because small molecules the size of water tend to be gases but water is a liquid. It is a liquid due to the hydrogen bonding between molecules.
Van der Waals forces. These forces are caused by temporary dipoles that develop due to fluctuations in electron distribution within molecules, leading to weak attractions between molecules.
This is an intermolecular attraction of water molecules, associated by hydrogen bonds.
Water molecules are held together by polar covalent bonds. These bonds are formed when oxygen shares electrons with two hydrogen atoms, resulting in a slight negative charge on the oxygen atom and a slight positive charge on the hydrogen atoms.
