Which one of the following molecules will form a linear polymeric structure due to H-bonding?
Which one of the following molecules will form a linear polymeric structure due to H-bonding?
$\mathrm{HCl}$
HF
$\mathrm{H}_{2} \mathrm{O}$
$\mathrm{NH}_{3}$
Solution
HCl does not form hydrogen bonds.
HF forms a linear polymeric structure due to strong hydrogen bonding.
$\mathrm{NH}_3$ does not form a polymeric structure due to weak hydrogen bonds.
$\mathrm{H}_2 \mathrm{O}$ forms a tetrahedral polymeric structure, not linear.
Thus, the correct answer is HF.
