explain the coordinate covalent bond formation between Nf3 and Bf3 , Nh3 andH
Answers
Answer:
Explanation:
NH3and BF3 molecules. In NH3 molecule N has a
lone pair of electron and in BF3 molecule B has an incomplete octet. So they choose
such type of joint-venture where NH3 invests its lone pair of electrons with BF3. In this
way NH3 helps BF3 to achieve octet. Now the bonded pair of electron is equally shared
Once the co-ordinate covalent bond is formed it is identical to the normal covalent
bond. Let’s try to solve the mystery of O3molecule. We have studied O2 molecule, it
has a double bond and two lone pair of electrons. It gives one of the lone pair to the
third O atom. Thus, O3 is formed by a double bond a co-ordinate covalent bond.
If you apply LCAO treatment for O3 molecule you will find its bond order is 1.5 which
shows that each O-O bond is formed by 1 sigma and half pi bond. The pi bond is
delocalised over all three O atoms. So the structure of O3 is best explained
by resonating hybrid.
