MCQ
The most volatile compound is
  • $2, 2-$ dimethyl propane
  • B
    $2-$ methyl butane
  • C
    Isobutane
  • D
    $n-$ pentane

Answer

Correct option: A.
$2, 2-$ dimethyl propane
a
The boiling point is inversely proportional to the branch in the compound. Therefore, $2,2$-dimethyl propane has more branching, higher boiling point.
