(0.5 pts) 5) Determine which of the molecules below contain polar covalent bonds AND use the appropriate symbols to represent the positive and negative poles. (1 pt) a) H-Br b) 1 c) H-O-H d) NF: 6) Determine the bond energy of the H-Br bond given the following: (0.5 pts) The bond energy of the H-H bond is 432 kJ/mol and the bond energy of the Br-Bo bond is 190 kJ/ mol.

Answer 1

The solution of the above questions is given below.

1) sol 15² 25² 206 35² 3p6 42 3ds 254 132 25 206 357 3p6 45 3110 Up 3 sol [Xe] 657 4 614 528 Mn As Pt Qy sol 112 25 20 35 3P 45 3 d. IS

are 05 Aug that contan polar covalent bonds The molecules HBl. Br.) hence all ove 2012 Here Charge Be is more etectronegitive will be collected there. H- O-H Here o is more electronegitine than H Here is more e-negitive than N Here Bond enegy of HH = 432 KI land = Ah, Boud energy of Bor Br = 193 keland - Alla The readion between Hydrogen and bromino is. H₂ + Bez - 24Br. het bond energy of H-Be be Ah- Bon Enkhelpy for the reaction will be given as. Ahi + Ally - 2 (Athy) = Haxh. Boud energy of HB = √ (Aht Ally - thxn). Al3 = + (625 - Ahaxn)
