Hey! IS THIS FROM THE NCERT SCIENCE BOOK?

Answered by saipronnatichauhan

is it correct

Explanation:

After boiling the leaf in water, it has to be boiled in alcohol so that chlorophyll is removed and the green colour of the leaf comes out. Boojho did not boil the leaf in spirit (alcohol) to remove the chlorophyll and therefore, he did not get the expected result (i.e. change in colour of the leaf).
