Why is HF a liquid when H2 is a gas?
The principal reason is the hydrogen bonding between HF molecules. The second reason is that London dispersion forces will be higher in HF because it has more electrons than H2
What molecules contains a covalent bond HF CN- LiCl MgO?
HF and CN- have covalent bonds.
Is HF an ionic or covalent?
a very polar, single, covalent bond, yes. This would be an ionic bond. The electronegativity of Hydrogen is about 2.2 and the electronegativity of Fluorine is about 4.0. The difference is 1.8 which is greater than 1.7, the minimum difference for an ionic bond. Or it is (at least) a very polar-covalent bond. Figures 1.7 or 1.8 are in the 'discussion' range
Which of the following molecules has a polar covalent bond iron oxide (Fe2O3) potassium chloride (KCl) bromine gas (Br2) hydrogen fluoride (HF)?
HF has a polar covalent bond.
How are frequency and energy of waves related?
Frequency and energy are related by the following: E = hf where h is Planck's constant, E is the energy in J, and f is the frequency in Hz. Remember that the product of any wavelength and its frequency is equal to the speed of light.
Why has HF higher boiling point than HCl?
becaus H-F forming hydrogen bond will the H-Cl dos'n
Why the bond energy of HF is greater than HBr?
Fluorine has the highest electronegativity of any element. Therefore, the energy released when hydrogen and fluorine react is greater than the energy released when hydrogen and bromine react, and that energy must be resupplied to cause either bond to break.
Is HF a weak bond?
HF is a weak polar bond
How is it possoble to predict if a bond is ionic or covalent?
When difference of electronegativity of two atoms is higher than 1.7 (exept HF) then bond is ionic or when a metals forms a bond with a non metal then it is usually ionic.
What is the bond type of HF?
HF (Hydrogen Flouride) is an ionic bond in all states.
What is true about a solution of 1.0 M HF?
HF has a higher [OH-] than a solution of 1.0 M HCl.
Why boiling point of H2O is higher then HF?
Both H2O and HF possess H bonds as their intermolecular force but H bonds of HF are stronger than that of H2o. therefore boiling point of than that of H2O. But experimental boiling point is high in H2O than that of Hf
What type of bonding HF is?
hydrogen bond
Does hf form hydrogen bond?
Yes, it can.
Why hydrogen bond in water is stronger than in HF and NH3?
In HF molecule hydrogen bonding is the strongest. The reason is that the partial positively charged hydrogen atom is entrapped between the two highly electronegative fluorine atoms.
What covalent bond is most polar?
A good candidate would be the bond in HF.
Why is HF a liquid when H2 is a gas?
The principal reason is the hydrogen bonding between HF molecules. The second reason is that London dispersion forces will be higher in HF because it has more electrons than H2
