AѕСІз OD. SIHA E. SICA QUESTION 3 What is the maximum num er of hybridized orbitals formed by an oxygen atom? QUESTION 4

Answer 1

6 A bond is polar when the atoms forming bond have high electronegativity difference. a) HS has HS bonds Elector negative difference = 2.5-2.1 = 0.4 b) PH₂ has P-H bonds En difference of P and H=2-1=2-1=0 c) Asla has . As ce bonds En difference = 3.0-261=0.9 d) Sitiu has Sint bonds EN difference = 2.1-118 = 0.3 e) sicly has since bonds En difference = 3:0-18=102 Highest difference of electronegativity is in since bond, so most polar. . Answer E) silly. (3.) Atomic number of oxygen (0)= 8 Electronic configuration of O= 15² 25² 2p/ O F 12 171111 Valenue shell Couturmat) participati to town hybrid orbitals. here 25 and 3-2p orbitals can form hybrid arbitals so Answer 4
