10/30 notes

Question 1

delocalized pi system

Answer 1

1)resonance structure where the pi bond moves
2)alternating single and multiple bonds

Question 2

what type of IE do metals have

Answer 2

low IE so it is easier for them to lose an electron

Question 3

what is in between the lattice shape of metals

Answer 3

sea/cloud of electrons

Question 4

what are the four traits of a metal

Answer 4

solids, conductors, malleable, insoluble

Question 5

why are metals solid

Answer 5

attraction between metal ion and sea of electron is strong, forms 3D lattice

Question 6

are metals conductors, why?

Answer 6

yes, because they have mobile electrons

Question 7

are metals malleable

Answer 7

yes and ductile, they bend rather than break

Question 8

what are the allotropes of carbon

Answer 8

diamond and graphite

Question 9

hybridization and molecular shape of diamond

Answer 9

sp3 hybridization and tetrahedrally connected

Question 10

graphite hybridization and molecular shape

Answer 10

sp2, forms flat sheets layer on top of each other

Question 11

pi system formed by graphite

Answer 11

delocalized

Question 12

can graphite conduct electricity

Answer 12

yes

Question 13

what are two giant covalent compounds

Answer 13

graphite and diamond

Question 14

what are the three properties of metallic solids

Answer 14

1) solids: attraction between metal and sea of electron is strong; forms 3D lattice
2) conductors: has mobile charged ions
3)malleable: bends rather than breaks
