Be2 Is Stable
And Diamagnetic, Bit Li2 Is Unstable.
What is the bond order for Be2?
molecule will be formed by the overlapping of atomic orbitals of
two
beryllium atoms. molecule has eight electrons which are to be filled in four molecular orbitals. molecule. So, the correct answer is “Option D”.
Why Li2 is unstable?
Li2 is
more stable than
Li+2 , because the bond is (hypothetically) stronger (probably gas-phase). for each electron in a bonding MO, it adds 0.5 to the bond order, because more bonding character strengthens the bond…
Is B2 2 stable or unstable?
When we calculate the bond order we find for B2 molecule it is 2,and for H2 and Li2 it is 2 for both. This clears that between these three molecules B2 will
be most stable
as it has highest bond order,and when the bond order is high it indicates that atoms are tightly held to each other making the molecule stable.
Is Be2+ stable or unstable?
Be2+ has a bond order of 0.5 and is slightly lower in energy than isolated Be atoms. It will probably exist under special experimental conditions but
be unstable
.
Does Li2 2 exist?
The bond order for the theoretical molecule Li22+ is zero (0) indicating no molecule of that type forms and therefore
does not exist
.
Why Li2 is stable and Be2 is unstable?
Nb= Number of electrons in bonding orbitals Na= Number of electrons in anti-bonding orbitals According to Molecular Orbital Theory If Nb > Na, the molecule is stable If Nb=Na, the molecule
is unstable If Nb<Na
, the molecule is unstable The Molecular Orbital Configuration of Li2 is [σ1s]^2 [σ*1s]^2 [σ2s]^2 Bond Order = …
Is F2 or F2+ more stable?
Between F2, F2+, and F2_ which do you think would have the highest bond order, strongest bond, longest bond length. … Therefore
F2+ will have the
highest bond order and strongest bond F2- will have the weakest bond and therefore the longest bond.
Which is more stable Li or Li+?
Also Li atom is
more stable than Li+
. However, in aqueous medium, due to extremely large hydration energy (energy evolved when a substance is hydrolysed), in aqueous medium, Li+ is more stable.
Is Li more stable than be?
Due to the small size of Li+ , the lattice energy of LiH is greater. As the size of the ion is small it has more force of attraction and hence it requires a lot of energy to break the bond and therefore it is
more stable
. Now, let’s discuss some of the properties of lithium. Hence, option A is correct.
How many bonds are there in Be2?
The two boron atom is B2 molecules are linked by
one covalent bond
. 2p
y
MO contains unpaired electron, therefore B
2
molecule is paramagnetic.
Is Li2 a bond order?
The molecule Li2 is a stable molecule in the gas phase, with a bond order of
one
. Bond Order=2(bonding electrons)−0(anti−bonding e−)2=1.
How do I calculate bond order?
- Draw the Lewis structure.
- Count the total number of bonds.
- Count the number of bond groups between individual atoms.
- Divide the number of bonds between atoms by the total number of bond groups in the molecule.
Is C2 +2 stable?
According to the molecular orbital diagram of the (C2)2+ ion you
its a stable ion
, because it has a bond order of 1 & that means its a stable substance.
Is f2 unstable?
Fluorine being a small atom cannot form stable bond with other fluorine atoms , because
it leads to a unstable structure
.
Is B2 +2 paramagnetic?
B2 has two unpaired electron so it is paramagnetic
whereas C2 has only paired electrons so it is diamagnetic. B
2
has 2 unpaired electron so it is predicted to be paramagnetic whereas C
2
has only paired electrons so it is predicted to be diamagnetic but not paramagnetic. …
