Which intermolecular force would affect melting point the most?
Hydrogen bonding
Why would the cohesion and therman stability of water be less if water did not have polar covalent bonds?
The highly polar nature of the H-O bond in water creates a stable dipole moment in the molecule, in other words it creates a slightly positive end (the hydrogens) and a slightly negative end (the oxygen). This allows one molecule of water to interact with another causing them to align. The hydrogen of one water molecule interacts with the oxygen of a different water molecule. This process of a highly polar bond containing a hydrogen interacting with another polar bond is referred to as hydrogen bonding. Chemists have determined that hydrogen bonding has a bond dissociation energy of ~23kJ/mol. Without the polar covalent O-H bond the hydrogen bonding would not occur and this would cause the cohesion and thermal stability to greatly reduced.
Does H2SO4 have hydrogen bonding?
No, H2SO4 does not have hydrogen bonding as it does not contain hydrogen atoms directly bonded to highly electronegative atoms like fluorine, oxygen, or nitrogen. Hydrogen bonding occurs when hydrogen is directly bonded to these electronegative atoms.
What is the difference between intra-molecular bonding and inter-molecular interaction?
Intermolecular is the bonding between the molecules (what connects them all together) For example dispersion, dipole-dipole, hydrogen bonding (HFON)Intramolecular is the bonding between the atoms like ionic covalent or metallic.For example in a water molecule the intermolecular bonding would be the hydrogen bonding. The non-bonding pairs will connect with other water molecules non-bonding pairs to create a hydrogen bond. Whereas the intramolecular bonding would be covalent. Because that's what joins the individual hydrogen atoms to one oxygen atom.
In what conditions would hydrogen bonding been present?
Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative atom like oxygen, nitrogen, or fluorine. It is present in molecules such as water (H2O), ammonia (NH3), and hydrogen fluoride (HF) under conditions where these electronegative atoms form a strong interaction with the hydrogen atom.
What would the world be like without the hydrogen bonding of water molecules?
Dry
In what situations would hydrogen bonding most likely occur?
Between H2O molecules. ( when hydrogen is covalently bonded to an electronegative atom)
Which intermolecular force would affect melting point the most?
Hydrogen bonding
Which of the intermolecular forces would affect boiling point the most?
Hydrogen bonding
Which intermolecular forces would affect boiling point the most?
Hydrogen bonding
What type of bonding holds the two strands of DNA together and why is this important?
hydrogen bonding between the two bases present on two strands of dna hold the two strands. If there was no hydrogen bonding then doublex helix structure of dna would not be possible

What levels of protein structure would be affected if all hydrogen bonding interactions were prevented?
I don't get the question, but it won't work if its hydrogen bonds are broken.
What is the strongest intermolecular force in H2O?
I would imagine Hydrogen Bond. It is hydrogen bond because hydrogen fluoride and water have a large dipole. The electronegative atom attracts electrons away from the hydrogen atom leaving the hydrogen atom almost unshielded proton with a partial positive charge.
