Question

question 3 of 25
in which situation would hydrogen bonding be present?

a. when hydrogen atoms bond together to form h₂

b. when hydrogen exists as an ion in solution

c. when hydrogen is attached to n, f, or o

d. when hydrogen is attached to c, s, or p

Explanation:

Hydrogen bonding occurs when a hydrogen atom is covalently bonded to a highly electronegative atom (N, O, or F) and interacts with another electronegative atom. Option A is a covalent bond between H atoms, not hydrogen bonding. Option B is about H as an ion, not hydrogen bonding. Option D: C, S, P are not electronegative enough to form hydrogen bonds. Option C matches the condition for hydrogen bonding (H attached to N, F, or O).

Answer:

C. When hydrogen is attached to N, F, or O
