CnH2n+1OHC_nH_{2n+1}OH

How many types classify alcohols?

Three main types: primary, secondary, tertiary

What does alcohol classification depend on?

Which carbon has the OH-OH group and how many other carbons are bonded to it

Define primary alcohol (1°)

OH-OH on carbon connected to only one other carbon (or none)

General structure of primary alcohol

RCH2OHRCH_2OH

Define secondary alcohol (2°)

OH-OH on carbon connected to two other carbons

General structure of secondary alcohol

R2CHOHR_2CHOH

Define tertiary alcohol (3°)

OH-OH on carbon connected to three other carbons

General structure of tertiary alcohol

R3COHR_3COH
