Hydrogen bond is an attraction force formed when
Hydrogen atom donate its valence electron
Hydrogen atom share its valence electron
Hydrogen atom from a covalent compound that has bonded with more electronegativity atom such as F, O, N with nitrogen, oxygen or fluorine atom in another molecule
Hydrogen atom bonded with more electronegativity atom such as Fluorine, Oxygen and nitrogen from another molecule
Hydrogen atom from a molecule bonded with hydrogen atom from another molecule
Which of the following molecules DOES NOT have the hydrogen bond between the molecules?
Water, H2O
Ammonia, NH3
Carbon dioxide, CO2
Sulphur, S
Hydrogen, H2
Why do hair stick together when it is wet?
Because there are hydrogen bonds between water molecules with the protein molecules in the hair
Because there are hydrogen bonds between water molecules with protein molecules in the hair and water molecules with another protein molecules in the hair.
Because there are covalent bond between water and protein molecules
Because the water adhesive force is greater than the repulsion force
Because the Van Der Waals force between molecules are formed.
Which of the following phenomena is due to the presence of hydrogen bond?
[there will be multiple answer]
Easy to flip the pages in the book when fingertip is wet
burning of hydrogen gas in oxygen gas
Hair stick together when wet
Ethanol, C2H5OH soluble in water
Ethanol have higher melting and boiling point than chlorine molecules
How can dative bond be formed?
Hydrogen atom from a molecule bonded with another hydrogen atom from another molecule
Hydrogen atom that has bonded with more electronegative atom such as F, O,N form bond with F,O,N atom from another molecule
Lone pair of electrons from a non metal atom are shared with another hydrogen ion
Lone pair of electrons are released to make sure another atoms achieve stable octet electron arrangement
Which of the following particles when combined may results in the formation of dative bond?
Oxide ions, O2-
Hydrogen ion, H+
Chlorine atom
Ammonia molecule, NH3
Dative bond can be found in
Ammonia gas, NH3
Ion ammonium, NH4 +
Water, H20
Nitrogen, N2
Which of the following statements is correct about metallic bond?
Only found in between the atoms of alkali metal
Bond will get stronger when the atomic size increase
Formed between sea of electrons and the metal atoms
An electrostatic force between sea of electrons that is negatively charge with the positive charge of metal ion
Magnesium metal can conduct electricity because
there presence of dative bond
the presence of free moving ions
the presence of hydrogen bond that carry the current
the presence of delocalised electrons that are free to move and carry the charge
Diagram show a molecule of ammonia. If we have 2 molecules of ammonia, what are the possible bond can be found?
covalent bond
Hydrogen bond
dative bond
metallic bond
