Which of the follwing forms maximum number of hydreogen bonds?Either NH2 or H2O.And how may?

Answer 1

I think you meaned NH3. when we consider the no. of proton bridge(H-bond) per molecule,NH3 can form 3 P.bridges per molecule & H2O can form 2 P.bridges per molecule.
But when we consider the overall aggregation water is far superior,that is why, although the molecular wt. of NH3(17) is less than H2O(18), NH3 is a gas at room temp. while H2O is a liquid. This is because of the fact that a large no. of H2O molecules gets aggregated to increase the effective molecular mass to a large extent,however the extent in case of NH3 is much low becuse of the lower electronegativity of Nitrogen than Oxygen.
you will get an idea of aggregation of H2O molecules by the following fact. You can consider the whole water of a river to be a singe giant aggregation molecule! with formula(H2O)n where n may tend to infinity.

Answer 2

Both form the same number: 3
However NH2 is a radical so maybe you meant NH3 in that case NH3 can form 4 bonds and H20 only 3

Answer 3

NH2 can form the max no. of hydrogen bonds........ammonia:NH4 and in the case of water it can be hydrogen peroxide:H3O


hey plz xcuse me if i am wrong.....i hate chemistry and so its marks hate me........

Answer 4

certainly water.. hydrogen in water forms more bonds than hydrogen in ammonia.. it is because of the greater affinity of oxygen in water towards hydrogen of another water molecule... bonds cannot be numbered in liquid..

Answer 5

H2O.BECAUSE O HAS>ELECTRONEGATIVITY THAN N.H BONDS WILL BE MADE ONLY WHEN THE ELEMENT OTHER THAN H SHOULD POSSESS MORE ELECTRONEGATIVITY THAN H.HF WILL FORM THE MOST HBONDS.

Answer 6

H2O
