In BF3 , B-F bond length is 1.30A , where BF3 is allowed to be treated with Me3N, it forms an adduct , Me3N-BF3, the bond length of B-F in the adduct is a)Greater than 1.30A b)Smaller than 1.30A 3)equal to 1.30A 4)none?
Verified Answer
In BF3 , B-F bond length is 1.30A , where BF3 is allowed to be treated...
The answer is a.
In BF3, there is back bonding in between fluorinc and boron due to presence of p-orbital in boron.
In BF3, there is back bonding in between fluorinc and boron due to presence of p-orbital in boron.
back bonding imparts double bond characteristics.
As BF3 forms adjuct the back bonding is no longer present and thus double bond characteristic disappears. Hence, bond becomes a bit longer than earlier ( 1.30 A).

Answer:
To determine the bond length of B-F in the adduct Me3N-BF3, we need to consider the bonding characteristics and the electronic structure of the molecules involved.
Bond Length in BF3:
The B-F bond length in BF3 is given as 1.30 Å.
Formation of Me3N-BF3 Adduct:
When BF3 reacts with Me3N (trimethylamine), it forms an adduct called Me3N-BF3. This adduct is formed due to the coordination of the lone pair of electrons on the nitrogen atom with the vacant orbital of the boron atom in BF3.
Effect of Adduct Formation on B-F Bond Length:
The formation of the adduct Me3N-BF3 involves the sharing of electrons between the nitrogen and boron atoms. This sharing of electrons leads to the formation of a coordinate covalent bond between the two atoms.
The bond length of the B-F bond in the adduct is expected to be shorter than the bond length in the original BF3 molecule. This is because the formation of the coordinate covalent bond involves the donation of electron density from the nitrogen atom to the boron atom, resulting in a stronger bond.
Comparison of Bond Lengths:
Given that the B-F bond length in BF3 is 1.30 Å, we can conclude that the bond length of B-F in the Me3N-BF3 adduct is smaller than 1.30 Å.
Summary:
In summary, the bond length of B-F in the Me3N-BF3 adduct is smaller than 1.30 Å. This is due to the formation of a coordinate covalent bond between the nitrogen and boron atoms, resulting in a stronger bond.
