12.Which of the following compound has the highest boiling point…………… a)Sec butyl chloride b)n-butyl chloride c)iso butyl chloride d)tert.butylchloride

Solution

Since, the most symmetrical structure out of these is of n-butyl chloride and as the branching increases, the symmetry decreases and the boiling point decreases.
So, n-butyl chloride has highest boiling point.
