The type of isomerism exhibited by the compound with formula C4H10O is
Chain, position, functional, and metamerism.
D.U. in C4H10O=(2nC+2)−nH2=10−102=0 it should be alcohol or ether.
i) Alcohols and ethers are functional isomers.
ii) Alcohol shows position and chain isomerism.
iii) Ether shows position isomerism and metamerism.
So the compound (C4H10O) shows chain, position, functional isomerisms, and metamerism.
