Question

Consider the following $$statementsI)$$ 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

Infinity Learn · Accepted Answer

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.
