Which of the following is the correct order in the above diagram increasing boiling point, of the isomeric C5H12 compounds?
A.
A
B.
B
C.
C
D.
D
E.
E
Correct answer is D
The boiling points of each of the compounds:
Pentane - 36.1°C ; 2- methylbutane - 27.8°C ; dimethylpropane - 10°C.
Therefore, the order of boiling point in ascending order is Dimethylpropane < 2-methylbutane < pentane.
