What are the factors that affects the bonding? (3+2+2)i. AsCl3ii. H2Oiii. BF3

The factors that affect bonding in AsCl3, H2O, and BF3 are:

i. AsCl3 (Arsenic Trichloride):

1. Electronegativity: Arsenic has a lower electronegativity than chlorine, which means chlorine will pull the shared electrons closer to itself, creating a polar covalent bond.
2. Atomic Size: Arsenic has a larger atomic size than chlorine, which can affect the bond length and bond strength.
3. Electron Configuration: Arsenic has 5 valence electrons, and chlorine has 7. Each chlorine atom will share one electron with arsenic to complete its octet, forming a covalent bond.

ii. H2O (Water):

1. Electronegativity: Oxygen is more electronegative than hydrogen, so the shared electrons will be closer to the oxygen atom, creating a polar covalent bond.
2. Atomic Size: Oxygen has a larger atomic size than hydrogen, which can affect the bond length and bond strength.
3. Electron Configuration: Oxygen has 6 valence electrons, and hydrogen has 1. Each hydrogen atom will share one electron with oxygen to complete its octet, forming a covalent bond.

iii. BF3 (Boron Trifluoride):

1. Electronegativity: Boron has a lower electronegativity than fluorine, which means fluorine will pull the shared electrons closer to itself, creating a polar covalent bond.
2. Atomic Size: Boron has a smaller atomic size than fluorine, which can affect the bond length and bond strength.
3. Electron Configuration: Boron has 3 valence electrons, and fluorine has 7. Each fluorine atom will share one electron with boron to complete its octet, forming a covalent bond.
