In the following compounds, the decreasing order of boiling point is

C{H_3} - C{H_2} - C{H_2} - C{H_2} - C{H_2} - C{H_3}

C{H_3} - \mathop {CH}\limits_{\mathop |\limits_{C{H_3}} } - C{H_2} - C{H_2} - C{H_3}

C{H_3} - \mathop C\limits_{\mathop |\limits_{C{H_3}} }^{\mathop |\limits^{C{H_3}} } - C{H_2} - C{H_3}

View answer and explanation

Correct option: A

I > II > III

Option A (

I > II > III

) is correct because boiling point decreases with increased branching due to reduced surface area and weaker van der Waals forces.
