What is the difference between normal butane and isobutane?

Normal butane is a liquid, while isobutane is a gas.

Normal butane is more flammable than isobutane.

The main difference is their molecular structure: normal butane has a straight-chain structure, while isobutane has a branched-chain structure.

Normal butane has a higher molecular weight than isobutane.
