Point at which lines are intersecting is denoted as carbon atoms
Number of atoms of different elements in following formulas:
1)
Number of hydrogen atom = 8
Number of carbon atoms = 3
Number of oxygen atoms = 1
2)
Number of hydrogen atom = 8
Number of carbon atoms = 3
Number of oxygen atoms = 1
3)
Number of hydrogen atom = 8
Number of carbon atoms = 3
Number of oxygen atoms = 1
