Bonding - Electronegativity and Polarity
Flashcards do conjunto (7)
- 1ElectronegativityAbility to an atom to attract a shared pair of electrons towards itself
- 2Difference in EN and bond typeCov - 0
Polar cov - 0 ->1.8
ionic > 1.8 - 3What is a pure covalent bond?Bond between two atoms of same electronegavity i.e. H-H
- 4Polar covalent bondUneven distribution in charge delta -/+
Dipole in a polar covalent bond is a PERMANENT DIPOLE - 5Draw diagram showing dipoles in CO2 and H2Oe.rg
- 6Which molecule is polar?H2O
Molecule is asymmetrical, permanent dipoles don't cancel each other - 7Trends in electronegativityIncrease charge = ^ EN
Decreased radius = ^ EN
Decreased shielding = ^ EN
Increases across a period
Decreases down a group
