A classification of fallacy that is widely accepted is the classification of fallacies into two groups "formal fallacies and informal fallacies".

What is the fallacy and definition of the Hypothetical Syllogism

Here are a few examples along with my initial response, but it doesn't appear that I got them right (although I don't know what the correct answer would be). Your assistance is greatly appreciated.
I thought this was Denying the Consequent:
If I master critical thinking then I will be a better employee
I am not a better employee
Therefore, I did not master critical thinking.
I thought this would be Deny the Antecedent:
If I can master critical thinking
then, I will be a better employee
I haven't mastered critical thinking
therefore I am not a better employee.
For the next statement I thought it contained two fallacies: Appeal to Ignorance and Appeal to Authority.
