C4H8O (molecular)
CH3CH2C(O)CH3 (structural) just incase its needed.
Answer: Talking about the progress of a chemical reaction all the three statements are correct because;
(1) When a reaction is occurring the spontaneous change occurs in the direction where equilibrium will be achieved.
(2) Exothermic reactions are those in which the release of heat energy happens. And when there is release of energy in a reaction, the reaction will be spontaneous.
(3) In a chemical reaction, law of energy conservation applies, which means the mass of reactant we started with will be equal to the mass of product obtained.
Hence, (d) is the right choice.
The velocity for the forward reaction equal that of the reverse reaction.
H-F because it has the largest difference in electronegativity which is 2, so it’s the most polar.
