Bonding In Compounds

Question 1

A pure covalent bond can be only found when

Answer 1

The electrons are shared equally

Question 2

Usually one atom in a covalent bond does what

Answer 2

Pulls the electrons closer - forming a polar covalent bond

Question 3

How does the Electronegativity affect how polar the bond is

Answer 3

Big difference in Electronegativity = more polar. Small difference = less polar

Question 4

The more ionic character a covalent bond has means what?

Answer 4

It is more polar

Question 5

Polar covalent bonds form when

Answer 5

The difference in Electronegativity is small

Question 6

Higher Electronegativity of an atom means what after bonding

Answer 6

That atom has a slightly negative charge

Question 7

Polar molecules mean what

Answer 7

Permanent dipoles exist

Question 8

Intermolecular forces are stronger in what type of bonding (non-polar or polar)

Answer 8

Polar

Question 9

More energy is required to melt what?

Answer 9

Polar covalent compounds

Question 10

If polar bonds are symmetrical - what happens to the polarity

Answer 10

The polarity is cancelled out

Question 11

If you want to dissolve a polar compound what will dissolve it?

Answer 11

Another polar compound - like dissolves like
