{'molecular weights': [0, 0, 1, 0], 'hydrocarbons': [1, 0, 2, 5], 'methane': [0, 0, 0, 5], 'butane': [0, 0, 5, 5], 'order': [6, 12, 34, 35], 'propane': [1, 0, 4, 4]}
The correct sequence in increasing order of molecular weights of the hydrocarbons is:
Methane, Ethane, Propane, and Butane.
Methane (CH4) has the smallest molecular weight among the given hydrocarbons.
Ethane (C2H6) has a higher molecular weight than methane.
Propane (C3H8) has a higher molecular weight than ethane and methane.
Butane (C4H10) has the highest molecular weight among the given hydrocarbons.
Therefore, the correct sequence in increasing order of molecular weights is Methane, Ethane, Propane, and Butane.
