✔ 最佳答案
They are both C4H10O, alcohol, but they different structures. Butanol:
CH3CH3CH3CH3OH
methylpropan-2-ol:
/OH
CH3CCH3
\_CH3
So, one methylpropan-2-ol take more spaces.
The density is then lower

^ right
you should got the best ans.
anyway
density related to the packing of molecules
rod shape pack better than that of branched molecule

You miss out something. You should state that the methylpropan-2-ol has a branched-chain while butan-1-ol has a straight chain first. The former one thus has a rod shape and the latter one has a sphere shape. More spaces are occupied between methylpropan-2-ol rather than probutan-1-ol.
