Polarity

Question 1

All bonds share electrons_____

Answer 1

equally or unequally

Question 2

what does dipole δ mean?

Answer 2

partial charge

Question 3

What bonds have partial charges?

Answer 3

Covalent, polar covalent

Question 4

What bonds don’t have partial charges?

Answer 4

ionic

Question 5

electronegativity

Answer 5

the ability of an atom to attract electrons

Question 6

How to determine the nature of a bond?

Answer 6

Find the electronegativity difference and minus them
Higher EN - Lower EN

Question 7

Nonpolar Covalent Bonds are

Answer 7

electrons shared evenly

Question 8

Polar Covalent bonds are

Answer 8

Atom with a higher EN that is partially negative and another atom with lower EN which is partially positive

Question 9

Ionic Bonds are

Answer 9

the attraction is so strong, the electrons completely transfer

Question 10

Polarity of Molecules is

Answer 10

a polar molecule is a molecule that has one end of the molecule that is slightly positive and the other slightly negative due to the unequal distribution of electrons

Question 11

How to determine molecular polarity

Answer 11

the polarity of the bond
shape of the molecule

Question 12

What is the symmetry of the molecules

Answer 12

can be defined as a balance or regular arrangement of the atoms within the molecule

Question 13

Polar Molecules requirements/description

Answer 13

-must have polar bonds
Creating a partial positive end and a partial negative end
-Found in asymmetrical molecule/. has asymmetrically distribution of charges

Question 14

Nonpolar Molecules requirements/description

Answer 14

-have nonpolar bonds or polar bonds that are evenly distributed throughout the entire molecule
-Symmetrial distribution of charges

Question 15

If a molecule doesn’t contain any polar covalent bonds then it is

Answer 15

nonpolar molecule

Question 16

If the polar bonds are symmetrical then

Answer 16

it is a nonpolar molecule

Question 17

if the polar bonds are asymmetrical then

Answer 17

it is a polar molecule

Question 18

What is solubility?

Answer 18

chemical property referring tot he ability for a given substance, the solute, to dissolve in a solvent

Question 19

what makes up a solution

Answer 19

solute and solvent

Question 20

What does soluability depend on

Answer 20

the structure/charges of the particles of the compount

Question 21

What do polar molecules and ionic compounds dissolve in?

Answer 21

polar solvents

Question 22

What do nonpolar molecules dissolve in

Answer 22

nonpolar solvents

Question 23

What do compounds with partial or complete charges dissolve in

Answer 23

compounds with partial or complete charges

Question 24

What do compounds with no charges dissolve in

Answer 24

compounds with no charges

Question 25

What happens to an ionic compound if it is soluable?

Answer 25

the ions dissociate, they separate, the water pulls the ionic crystal apart

Question 26

How do Covalent compounds dissolve?

Answer 26

the molecules separate rom each other, the solubility depends on the attractions between the molecules when they have charges

Question 27

How does sugar dissolve in water?

Answer 27

The positive and negative forces of water attract the sugar molecules and pull individual molecules away from the entire crystal, until all the molecules are separated and surrounded by water
