How many hydrogen atoms are there in one molecule of toluene?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. 8.
Toluene is an organic compound with the chemical formula C7H8. Its structure consists of a benzene ring (C6H5-) with one of its hydrogen atoms replaced by a methyl group (-CH3). So, there are 5 hydrogen atoms on the benzene ring and 3 hydrogen atoms in the methyl group, totaling 8 hydrogen atoms.
