Which of the following has the strongest bond:
CH4
NH3
HF
H2O
Based on the lecture given by my teacher I know that the more electrons involved in a compound the shorter and stronger bond they have, thus is seen drawing the Lewis Structure. But, Since all of these only make a single bond I have no idea how to tell which one has the strongest bond.
Yes they are all single bonds
Yes they are all single bonds. However as you move across the table, from L to R the number of protons increases eg C, N, O and F. This causes the atoms to get smaller from L to R. The greater attraction for electrons from L to R is shown by increased electronegativity values. F is the most electronegative element in the periodic table. So the values increase from C ---> F. As electronegativity is a measure of the attraction an atom has for a pair of shared electrons it means that the strongest attraction is between H and F and the weakest between C and H.
