Which of the following factors affects the strength of hydrogen bonding?
Electronegativity of the donor atom
Size of the donor atom
Steric hindrance around the donor atom
All of the above
The strength of hydrogen bonding is affected by several factors, including the electronegativity of the donor atom, the size of the donor atom, and the steric hindrance around the donor atom. The more electronegative the donor atom, the stronger the hydrogen bond. Smaller atoms can form stronger hydrogen bonds, and steric hindrance around the donor atom can weaken or prevent hydrogen bonding.
