How would you name the following compounds - Teachoo.jpg

Answer:

ANS: 

1). Since the structure has 2 carbon atoms connected only by single bonds , hence we will call it ‘ ethane ’.

  • A Br atom is attached to the chain. 
  • We start counting from both ends of the chain. From one end we get, 2 Bromo-ethane , and from the other end we get, 1-Bromo ethane.
  • We always take the count where the functional group has the least count (position).
  • Hence, the compound is named as, 1-Bromo ethane.
  •  

2). There is a single carbon atom hence, we use Meth and an aldehyde group present, so we add - al, combining we get Methanal.

 

3). 6 carbon atoms are present, hence we use ‘hex’. 

  • There is a Triple bond at the 1st position . Why not the 6th position? Because we always take the count where the functional group has the least count (position).
  • Hence, we get Hex-1-yne.
