Question: EXTENT OF BACK BONDING IS MORE IN B(NH2)3 THEN B(OH)3 THEN BF3?...

EXTENT OF BACK BONDING IS MORE IN B(NH2)3 THEN B(OH)3 THEN BF3?

Answer

True

Explanation

Solution

Back bonding extent is inversely proportional to the electronegativity of the donor atom. Nitrogen (in B(NH2)3) is the least electronegative (best donor), followed by Oxygen (in B(OH)3), and then Fluorine (in BF3) is the most electronegative (poorest donor). All involve efficient 2p-2p orbital overlap. Thus, the order of back bonding is B(NH2)3 > B(OH)3 > BF3.
