Polarity

Question 1

Polar Bonds

Answer 1

significant difference of electronegativity between two atoms; unequal share of electrons

Question 2

Polar Molecule

Answer 2

Molecule where regions of positive and negative charge present on either end.

Question 3

Polar Parts of Molecule

Answer 3

Molecule is asymmetrical, has lone pairs, dipole-dipole moments do not cancel

Question 4

Relationship between Polarity and Intermolecular Forces

Answer 4

Polarity affects strength of Intermolecular Forces (Stronger IMF = Stronger Polarity)

Question 5

Relationship between Polarity and Solubility

Answer 5

Polar Solutes are more soluble in Polar Solvents. (Due to edge action of opposite charges)
Non polar Solvents more soluble in Polar solvents. (Cannot attract dipoles or ions)
