what are structural isomers? Draw the 2 isomers of butane
Molecules having same molecular formula but different structure are said to be structural isomers.
They are of 4 types
1. chain isomerism :- In this there is difference in arrangement of carbon atoms
2. position isomerism :- In this , there is difference in position of same functional groups
3. functional isomerism :- In this , the compounds have same molecular formula but have different functional groups
4. metamerism :- this arises due to unequal distribution of alkyl gropus on either side of functional group in the molecules ...
For example Butane has 2 isomers
1. n-butane
2. iso-butane (2 methyl propane)
Hope this helps !!
