Water molecules are held together by hydrogen bonding. This occurs because the oxygen atom, being more electronegative, creates a partial negative charge, while the hydrogen atoms acquire a partial positive charge. These polar characteristics allow the positively charged hydrogen atoms of one water molecule to attract the negatively charged oxygen atoms of neighboring water molecules, forming hydrogen bonds.
What else can I help you with?
Why kind of molecule can experience hydrogen bonding?
Hydrogen bonding occurs in molecules that contain hydrogen atoms covalently bonded to highly electronegative elements, specifically nitrogen (N), oxygen (O), or fluorine (F). These electronegative atoms create a significant dipole, allowing the hydrogen atom to interact with lone pairs of electrons on other electronegative atoms in nearby molecules. Therefore, molecules like water (H₂O), ammonia (NH₃), and hydrogen fluoride (HF) can all experience hydrogen bonding.
In what situations would hydrogen bonding most likely occur?
Between H2O molecules. ( when hydrogen is covalently bonded to an electronegative atom)
Can cf4 form a hydrogen bond?
No, carbon tetrafluoride (CF4) cannot form hydrogen bonds. Hydrogen bonding typically occurs when hydrogen is bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine, which can attract hydrogen atoms from other molecules. In CF4, the carbon is bonded to four fluorine atoms, and while fluorine is electronegative, there are no hydrogen atoms present in CF4 to participate in hydrogen bonding.
Is cohesive strength a result of hydrogen bonding?
Yes, cohesive strength in materials like water is due to hydrogen bonding. Hydrogen bonding occurs when hydrogen atoms covalently bond with highly electronegative atoms like oxygen, creating a strong dipole-dipole interaction that holds molecules together. This results in the cohesive properties of substances, such as high surface tension and viscosity.
Which of the following intermolecular forces plays a pivotal role in biological molecules such as proteins and DNA?
Hydrogen bonding is the intermolecular force that plays a pivotal role in biological molecules such as proteins and DNA. Hydrogen bonds are formed between hydrogen and electronegative atoms such as oxygen or nitrogen, influencing the structure and function of these important biomolecules.
Why does hydrogen bonding do not take place between molecules of aldehydes and ketones?
Hydrogen 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.
Is H2S capable of hydrogen bonding?
No, H2S is not capable of hydrogen bonding because it does not contain a hydrogen atom bonded directly to a highly electronegative atom (such as nitrogen, oxygen, or fluorine). Hydrogen bonding occurs between molecules with a hydrogen atom bonded to a highly electronegative atom and another electronegative atom.
Is CH3CH2OH a Hydrogen Bond?
Yes, CH3CH2OH (ethanol) can participate in hydrogen bonding. Hydrogen bonding occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (such as oxygen in this case) and is also attracted to another electronegative atom. In ethanol, the hydrogen atom bonded to the oxygen can form hydrogen bonds with other electronegative atoms, such as oxygen or nitrogen in other molecules.
Is C6h6 capable of hydrogen bonding?
No, benzene (C6H6) does not have hydrogen bonding capabilities as it lacks hydrogen atoms directly bonded to highly electronegative atoms like fluorine, oxygen, or nitrogen. Hydrogen bonding requires a hydrogen atom bonded to a highly electronegative atom and a lone pair of electrons on another electronegative atom.
Does pentane have hydrogen bonding?
No, pentane does not have hydrogen bonding because it does not contain any hydrogen atoms bonded to highly electronegative atoms like oxygen, nitrogen, or fluorine. Hydrogen bonding occurs between molecules containing hydrogen atoms bonded to these electronegative atoms.
Is he hydrogen bonding?
Hydrogen bonding occurs when a hydrogen atom is covalently bonded to an electronegative atom (like oxygen or nitrogen) and forms a weak attraction with another electronegative atom. It generally involves molecules that contain hydrogen bonded to fluorine, oxygen, or nitrogen.
Why kind of molecule can experience hydrogen bonding?
Hydrogen bonding occurs in molecules that contain hydrogen atoms covalently bonded to highly electronegative elements, specifically nitrogen (N), oxygen (O), or fluorine (F). These electronegative atoms create a significant dipole, allowing the hydrogen atom to interact with lone pairs of electrons on other electronegative atoms in nearby molecules.

Does so3 have hydrogen bonding?
No, SO3 does not have hydrogen bonding because it does not contain hydrogen atoms bonded to highly electronegative atoms such as oxygen, nitrogen, or fluorine. Hydrogen bonding requires hydrogen atoms directly bonded to these electronegative atoms.
Is the tendency of water molecules to attract one another due to polarity is called ionic bonding?
No, the tendency of water molecules to attract each other is due to hydrogen bonding, not ionic bonding. Ionic bonding occurs between ions of opposite charges, while hydrogen bonding occurs between a hydrogen atom bonded to an electronegative atom (like oxygen) and another electronegative atom.
What are intermolecular hydrogen bonds?
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.
Is hydrogen bonding strongest between molecules of H20 H2S H2Se or H2Te?
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.
In what conditions would hydrogen bonding be present?
Answer this question…When hydrogen is attached to N, F, or O
