Question

Give any four functional groups containing oxygen as the heteroatom in it. Write name and structural formula of one example each. Write answers as directed

Answer 1

The four functional group which contains Oxygen as the hetreroatoms are :-

⇒   (i)    R- OH (Alcohol) 
⇒   (ii)   R-O-R (Ether)
⇒  (iii)   R-CHO (Aldehyde)
⇒  (iv)   R-COOH (Carboxylic acid) 

Example, Names & Structural formula ⇒

For R- OH (Alcohol)

CH₃-CH₂-OH ---→ Ethanol
