Question

Which compound form linear polymer due to H-bond:

• A. $H_2O$
• B. $NH_3$
• C. $HBr$
• D. $HCl$

Answer 1

Answer: (B)

$NH_3$

Answer 2

Ammonia $(NH_3)$ can form linear chains or polymers through hydrogen bonding between ammonia molecules, leading to the formation of $NH_3NH_3NH_3.….$ chains. This hydrogen bonding is responsible for some of the unique properties of ammonia, such as its high boiling and melting points.

So, the correct option is (B): $NH_3$
