Week 3 Day 1

Contain carbon-carbon single bonds and carbon-hydrogen bonds BP increases with increasing molecular weight, so larger Alkanes are less volatile than smaller ones

CH4

C2H6

C3H8

C4H10

C5H12

C6H14

C7H16

C8H18

C9H20

An Alkane minus a Hydrogen. In place of Hydrogen, the alkyl will bond to something else.

• 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

Alkanes that form a ring. Prefix name with “cyclo-“

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