Question

Hydrocarbons having the same formula but variations in structure are called isomers.

True or False?

Answer 1

The definition for isomers is that those are two compounds with the same element composition but different structure. The same number of atoms of the given element makes up the molecules but the bonding is different. E.g. in hydrocarbons, C4H10 can correspond to a straight 4-atom chain or a 3-atom chain and one methyl substituent bonded to the second carbon atom.
