Correct answer
Cchemical bond formation takes place when forces of attraction overcome the forces of repulsion
Step-by-step explanation
(A) Electronegativity of F is 4 and Electronegativity of H is 2.1.
Electronegativity difference between F and H is = 4 - 2.1 = 1.9
Now Electronegativity of Br is 2.8 and Electronegativity of H is 2.1.
Electronegativity difference between Br and H is = 2.8 - 2.1 = 0.7
As in HF Electronegativity difference is more then it's polar nature is also more.
(B) At equilibrium pure H2O produce very less H+ and OH- ions.
(C) Chemical bond formation takes place when forces of attraction overcome the forces of repulsion.
(D) In covalenrt bond, sharing of electons take place. Transfer of electrons take place in ionic bond.
