The chemical reaction equation for acetylene to ethane in the presence of excess hydrogen can be written in terms of two-step synthesis, but the reaction of methane and chlorine in the presence of light can not be four-step in one step, because each step can not proceed to the end and the degree of each step is different.

If the boiling point of alcohol is 78°C, the following statements are correct: A 78°C alcohol must boil B 78°C alcohol must not boil C 78°C alcohol may not boil D all the above statements are wrong If the boiling point of alcohol is 78°C, the following statements are correct: A 78°C alcohol must boil B 78°C alcohol must not boil C 78°C alcohol may not boil D is not correct

C.78°C Alcohol does not necessarily boil
Because boiling requires two conditions:
(1) The boiling point is reached;
(2) Continue to replenish heat.
