Question 1

Structure

Answer 1

the connectivity and 3D nature of compounds

Question 2

Bonding

Answer 2

the atoms and electrons that bind them

Question 3

Reactivity

Answer 3

how to design and make new molecules

Question 4

Formal charge

Answer 4

valence e - bonds - lone e

Question 5

Octet rule

Answer 5

• always holds for C, N, O
• more important than formal charge

Question 6

Formal charge trends

see goodnotes

Answer 6

Oxygen
Nitrogen
Carbon

Question 7

naming brached-chain alkanes

general structure + rules

Answer 7

prefix: substituents and locations
# on parent (1,2)
(carbon chain prefix) -yl
parent: # of C atoms in longest chain (3)
carbon chain prefix
suffix: functional group

1. # carbons to yield the lowest prefix
2. # carbons to alphabetically order subst.
3. if same length, chain with most branches

Question 8

naming carbon chain prefixes (1-10)

see goodnotes

Question 9

-F -Cl -Br -I

name substituents

Question 10

CH(CH3)2

name substituent

Answer 10

isopropyl

Question 11

-O(R) -OH

name substituents

Question 12

-C6H5 -CH2C6H5

name substituents

Question 13

naming rings

Answer 13

use prefix ‘cyclo’ + alkane
- number the chain so that subst. are in alphabetical order
- don’t put ‘1’

eg: methyl-3-propylcyclopentane
