Example-1: CH3
CH2
OH
Principal functional group : -OH (-ol)
Parent hydride : CH3
– CH3
Parent hydride + one Principal functional group ----> CH3
CH2OH
Example-3:CH3
-C-CH2
-CH2
-CH2
-CH2
-CH2
-OH
Principal functional group >(C) = O -one
Parent hydride CH3
-CH2
-CH2
-CH2
-CH2
-CH2
-CH3 Heptane
Parent hydride + Principal functional group
Note: In the solution the principal functional group >C=O (Keto) group
is given more priority than to –OH (alcohol).
Parent hydride CH3 – CH2 – CH2 – CH2 – CH2
Pentane
Principal functional group -OH -ol
Principal hydride + Principal functions Pentan – 2 – ol
