Answer:
Explanation:
Phenols upon treatment with dilute nitric acid undergo nitration at low temperature (298 K) to give a mixture of ortho and para nitrophenols.
The most common jack used for short travel distances is the single-stage variety. A single stage means that it is one piston that goes up and down and it does not telescope when it reaches a certain height. These can be used for passenger or freight elevators.
