प्रश्न
Arrange the following according to the instruction given in bracket:
C2H2, C3H6, CH4, C2H4 (In the increasing order of the molecular weight)
उत्तर
CH4 > C2H2 > C2H4 > C3H6
Explanation:
Molecular weight:
CH4 = 12 + 4 = 16
C2H2 = 12 × 2 + 2 × 1 = 26
C2H4 = 12 × 2 + 4 × 1 = 28
C3H6 = 12 × 3 + 6 × 1 = 42
