FTP, name this four-carbon alkane that follows propane and is commonly used as a household fuel and in lighters.
Most of its n, or normal, isomer is converted to its diene analog for use in synthetic rubber.  It has only one constitutional isomer, and their boiling points differ by an amazing 10 degrees.  That isomer, prefixed with an iso, exhibits a methyl group at either the second or third carbon.  The first of the alkanes that can exist as other than straight chain, its cyclic variety can simple be represented by a square.
