###### Question:

Normal text Arial 12. y BIU A 15 21 3. 4. 5. 6 1-What is the formal charges on B and Br (with double bond) in the following structure? a) 0,0 b) +1, + 1 C) -1, +1 d) 0, +1 :Br: Il B : Br Br: .. 2- The polarity of a covalent bond is due to (a) lesser electronegativity difference between two atoms (b) greater electronegativity difference between two atoms (c) lesser bond energy (d) greater bond energy 3- A CO, molecule contains two polar bonds, but the net dipole moment is zero. It is because: (a) the molecule has symmetrical linear geometry and dipole moments cancel out each other (b) the molecule is non-linear (c) the electronegativity difference between the two atoms is too large (d) the electronegativity difference between the two atoms is too small
