Week 3 Day 1 Flashcards
1
Q
Alkanes
A
Contain carbon-carbon single bonds and carbon-hydrogen bonds
BP increases with increasing molecular weight, so larger Alkanes are less volatile than smaller ones

11
Q
Alkyl
A
An Alkane minus a Hydrogen. In place of Hydrogen, the alkyl will bond to something else.
12
Q
How to name alkanes
A
- name the longest alkane. This is the parent chain
- name the substituent alkyl groups in alphabetical order
- us multipliers to indicate number of identical substituents (di, tri, tetra, penta)
- number the parent chain from the end. Start on side with substituents closest to the edge.
- Number the substituents
13
Q
cycloalkanes
A
Alkanes that form a ring.
Prefix name with “cyclo-“

A
Contain at least one carbon-carbone double bond as well as carbon-hydrogen bonds.
