Consider the following statements
I) among isomeric alkanes always straight chained has the higher Boiling point and Melting point.
II) Greater the branching in alkanes, lower will be its Boiling point.
III) M.P of alkanes depends upon the packing of molecules in the crystalline lattice
Select the correct statements
Aliphatic alkanes can get tightly packed and exhibit high density. But when branching increases the extent of packing decreases. Poor packing will result in the low boiling point.
