the physical properties of isomers of C4 H10
**Answer:**
There are two isomers: normal butane (n-butane) CH3(CH2)2CH3 and 2-methylpropane (isobutane) (CH3)3CH. This is colorless gases which are soluble in organic solvents and insoluble in water. 2-methylpropane forms crystalline hydrates. The melting and boiling points are different. Butane has a melting point of 135.4K and 2-methylpropane has a melting point of 114K. The boiling point of butane is 272.6K and isobutane is 261K. It has to do with there structures.
