The correct order of boiling point of 2,2-dimethyl-propane , 2-methylb

1.	The correct order of boiling point of 2,2-dimethyl-propane , 2-methylbutane and n-pentane is
Answer» n-pentane GT 2,2-dimethylpropane gt 2-methyl-butane n-pentane gt 2-methylbutane gt 2,2-dimethyl-propane 2-methylbutane gt n-pentane gt 2,2-dimethyl-propane 2-methylbutane gt 2 ,2-dimethylpropane gt n-pentane Solution :BOILING point DECREASES as BRANCHING increases, i.e., n-pentane gt 2-methylbutane gt 2,2-dimethyl-propane
