Chapter 21 Flashcards
1
Q
Line Notation Steps
A
- omit symbols for C and H (when bonded to C)
- each line is a bond
- fill in H to give each C 4 bonds
2
Q
Alkanes
A
Hydrocarbons (can be saturated or unsaturated)
3
Q
Saturated hydrocarbons
A
Only single bonds
4
Q
Unsaturated hydrocarbons
A
Have multiple bonds
5
Q
hydrogenation
A
adding hydrogen
6
Q
dehydrogenation
A
taking away hydrogen
7
Q
Properties of Alkanes
A
- LDF only
- low BP
- insoluble in water (nonpolar)
8
Q
Naming Alkanes
A
Add suffix “-ane”
ex) methane, ethane, propane, butane, pentane
9
Q
Naming Branches Alkanes (Steps)
A
- find longest C chain, name the alkane
- Name each branch (if alkane, end in ‘yl’ if halogen end in’o’
- count # C the branch is on
- # C-branchnamebasenameane
10
Q
Alkenes
A
hydrocarbon with at least one double bond
11
Q
Naming alkenes
A
- same as alkanes
- suffix “-ene”
12
Q
Alkyne
A
hydrocarbon with at least one triple bond
13
Q
Naming alkynes
A
- same as alkanes
- suffix “-yne”
14
Q
Naming multiple multiple bonds
A
- prefix # of multiple bonds before ‘ene’ or ‘yne’
- ex) 2,4-heptadiene
15
Q
Optical Isomers in hydrocarbons
A
when atom is bonded to 4 different groups
