Which alkane is the isomer of butane called 2-methylpropane? mc014-1.jpg mc014-2.jpg mc014-3.jpg mc014-4.jpg

Isomers have same formula but the different arrangement of atoms/ structure.

Butane is an alkane which has 4 carbon atoms. The formula is C4H10. 2-methyl propane is also an alkane which has 4 carbon atoms. The formula is also C4H10. Only difference in these compounds is 2-methyl propane has 3 carbon atoms in main carbon chain and there is CH3- group in 2nd C atom while butane has 4 carbon atoms in main carbon chain.

The structures are as the image.

it would be b. 6co2 + 6h2o --> c6h12o6 + 6o2
