The following compounds in order of decreasing strength of intermolecular forces is as follows :
CH₃CH₂CH₂CH₂CH₂CH₃ > (CH₃)₃CCH₂CH₃ > (CH₃)₃CCH₃
1) The following compounds in order of decreasing strength of intermolecular forces is as follows : as the surface are decreases the intermolecular force decrease or as branching increases intermolecular forces decreases.
CH₃CH₂CH₂CH₂CH₂CH₃ > (CH₃)₃CCH₂CH₃ > (CH₃)₃CCH₃
2) the compound CH₃CH₂CH₃ have the weaker van der wall forces and having the lowest boiling point.
