NOMECLATURE

Wood Root

This denotes the number of carbon atoms present in a given molecule. For e.g., C₁-Meth, C₂- Eth, C₃ - Prop, C₄- But.

Suffix

The suffix denotes the type of bonds or the functional group present in the carbon chain, e.g.

Type of bond	Functional group
'ane' (single bond)	'ol' for alcohols (-OH)
'ene' (double bond)	'al' for aldehydes (-CHO)
'yne' (triple bond)	'oic acid' for carboxylic acid (-COOH)

Prefix

This denotes the presence of other functional groups and their position.
For e.g., the following compound can be named as:

Word root: But (C₄) Prefix: 3, chloro
Suffix: -ol Name: 3-chloro butanol
Note carbon atoms are numbered from the side of the functional group (-OH in this case).
