Tip number 1 : If chemical compound has at least 1 element among 3 element (N, O, F)
Tip number 2 : Among 3 element (N, O, F) at least one element directly attach with H atom
Decision for Hydrogen bonding:
Tip number 2 : Among 3 element (N, O, F) at least one element directly attach with H atom
Decision for Hydrogen bonding:
If you find both tip 1 and 2 then given compound will must have H-bonding, if you do not find tip 1 and tip 2 then there will no H- bonding.
H2O, HF, C2H5OH, NH3, C5H5N, C6H12O6
Example :
H2O, HF, C2H5OH, NH3, C5H5N, C6H12O6
Note: CF3 does not have H-bonding , because the F atom in this compound is not directly attached with H atom
