When hydrogen is attached to the more highly electronegative oxygen atom in a water molecule?
When hydrogen is attached to a more electronegative element, the electronegative atom becomes partially negative and the hydrogen atom becomes partially positive
What else can I help you with?
Hydrogen bonding is a weak attractive force?
Hydrogen bonding is a type of intermolecular force that occurs when a hydrogen atom is covalently bonded to a highly electronegative atom like oxygen, nitrogen, or fluorine. This results in a partial positive charge on the hydrogen atom, which can then be attracted to the partial negative charge on the electronegative atom of a neighboring molecule. Hydrogen bonding is stronger than other types of dipole-dipole interactions but weaker than covalent or ionic bonds.
What causes polarity in water molecule?
When a highly electronegative atom is attached to a less electronegative atom, then the former one attracts the shared pair of electrons towards itself. Such a molecule is polar molecule. Polarity of molecule means the product of charge on molecule and the distance between the atoms.
Which molecule is most polar?
Water is the most polar molecule because of its bent shape and uneven distribution of charge, with oxygen being more electronegative than hydrogen. This leads to a positive side (hydrogen) and a negative side (oxygen) within the molecule, making it highly polar.
Is DNA a polar or nonpolar molecule?
DNA is a polar molecule because it has a negatively (-) charged phosphate group attached to the 5' end of the molecule and a negatively charge hydroxl group (OH) attached to the 3' prime end of the molecule.Thus, it is a POLAR molecule which allows it to interact in an aqueous environment.
The final electron acceptor of aerobic respiration is?
Oxygen, because it is highly electronegative.
Can NaF form Hydrogen bonds?
No, NaF (sodium fluoride) cannot form hydrogen bonds because it does not contain hydrogen atoms attached to highly electronegative atoms like fluorine, oxygen, or nitrogen that are necessary for hydrogen bonding. Hydrogen bonding typically occurs between hydrogen atoms bonded to these electronegative atoms and other electronegative atoms in a molecule.
Which molecule will not exhibit hydrogen bonding?
FON Remember this as it mean only hydrogen bonded to fluorine, oxygen and nitrogen will exhibit hydrogen bonding H2O ( water ) = hydrogen bonding as hydrogen is bonded to oxygen CO ( carbon monoxide ) = no hydrogen bonding Think electronegative differences.
Is c5h10 hydrogen bond?
No. In order for hydrogen bonds to form, hydrogen must be bonded to a highly electronegative element such as oxygen, nitrogen, or fluorine. In this molecule it is only bonded to carbon, which is not electronegative enough.
Is CHCL3 hydrogen bonding?
No, CHCl3 (chloroform) cannot participate in hydrogen bonding because it does not contain any hydrogen atoms bonded to highly electronegative atoms like nitrogen, oxygen, or fluorine. Hydrogen bonding occurs when hydrogen atoms are directly attached to these electronegative atoms.
What does not form hydrogen bonds is it hcn hf ch3nh2 ch3cooh or clch2oh?
ClCH2OH does not form hydrogen bonds because it lacks hydrogen atoms bonded directly to highly electronegative atoms like nitrogen, oxygen, or fluorine. Hydrogen bonding occurs between a hydrogen atom attached to an electronegative atom and another electronegative atom.
Do hydrogen bonds form from an equal charge distribution within a molecule?
No, hydrogen bonds do not form from an equal charge distribution within a molecule. Instead, hydrogen bonds occur between a hydrogen atom covalently bonded to an electronegative atom (such as oxygen, nitrogen, or fluorine) and another electronegative atom. This creates a partial positive charge on the hydrogen atom, which can interact with the partial negative charge on the electronegative atom of another molecule to form a hydrogen bond.
Is co2 hydrogen bond?
No, carbon dioxide (CO2) does not hydrogen bond. Hydrogen bonding occurs when a hydrogen atom is bonded to a highly electronegative element like oxygen, nitrogen, or fluorine, and forms a weak electrostatic interaction with another electronegative atom in a different molecule. Since there are no hydrogen atoms directly bonded to an electronegative atom in CO2, hydrogen bonding does not occur.
Do hydrogen bonds always involve hydrogen?
As far as I know: yes! They involve hydrogen bonded to an electronegative element (like oxygen). This Hydrogen in the molecule is then attracted to another electronegative element (like oxygen, nitrogen etc)
Are hydrogen bonds a example of adhesion?
Yes, hydrogen bonds can contribute to adhesion between molecules. Hydrogen bonds form between a hydrogen atom in one molecule and a highly electronegative atom in another molecule, leading to increased molecular attraction and potential adhesion.
What is the type of intermolecular force present in KOH?
The type of intermolecular force present in KOH is hydrogen bonding. Hydrogen bonding occurs between the hydrogen atom of one molecule and the oxygen atom of another molecule when hydrogen is bonded to a highly electronegative atom such as oxygen.
Does hydrogen experience a hydrogen bonding?
The hydrogen molecule, H2, consists of two hydrogen atoms joined by a covalent bond in which one pair of electrons is shared. The hydrogen molecule does not experience hydrogen bonding, as it is a nonpolar molecule.
What is the bond between hydrogen atoms on one molecule and a highly electronegative atom on another molecule but not a full covalent bond?
This is known as a hydrogen bond. It is a type of dipole-dipole interaction where hydrogen atoms are attracted to highly electronegative atoms, such as oxygen or nitrogen, due to the large difference in electronegativity between the two atoms. Hydrogen bonds are weaker than covalent bonds but stronger than typical dipole-dipole interactions.
