properties part 2 very important

Question 1

Why do we hybridize

Answer 1

We hybridize so orbitals can have the same energy to form a desired shape that is required. ut also allows for a molecule and orbitals to have equal bonds in energy

Question 2

what is formula unit

Answer 2

simplest ratio of ions therefore X4Y2 would just be X2Y

Question 3

know that these are all covalent networks

Answer 3

diamond, graphite,graphene,fullrene, Si, SiO2, SiC

Question 4

What is lattice structure

Answer 4

The forces of electrostatic attraction between ions in a compound cause the ions to surround themselves with ions of opposite charges, and as a result forming a 3D shape called lattice structure

Question 5

Structure about graphite

and Graphene

Answer 5

Each C atom is Sp2 hybridized and covalently bonded to 3 others, forming hexagons, LDF forces

Each C atom for Graphene is covalently bonded to 3 others with angles also of 120

Question 6

Structure of diamond

and fullrene

Answer 6

Diamond is Sp3 hybridized and covalently bonded to 4 others in tetrahedral 109.5

Fullrene is SP2 hybridized and bonded in sphere of 60 carbons
