In which situation would hydrogen bonding be present? A. When hydrogen exists as an ion in solution
B. When hydrogen is attached to C, S, or P
C. When hydrogen is attached to N, F or o
D. When hydrogen atoms bond together to form H2

C

Explanation:

hydrogen Bond exists between ammonia, hydrogen flouride and water so the answer is C

the seeing the electronic configuration we can say that the element is fluorine.

fluorine is the most electronegative element in the periodic table.

but by only seeing the configuration we cannot say about its reactivity because we don't know if its configuration after excitation or by addition of electrons.

but if not then, it is the lightest halogen and exists as a highly toxic pale yellow diatomic gas at standard conditions. as the most electronegative element, it is extremely reactive: almost all other elements, including some noble gases, form compounds with fluorine.
