Mar 14, 2018 · The bond angle in a molecule is inversely proportional to the electronegativity of the surrounding atom if the central atom is same. This also happens with $\ce {NH3}$ and $\ce {NF3}$, …

Jul 3, 2014 · The $\ce {H-N-H}$ bond angle in ammonia is around 107 degrees. Therefore, the nitrogen atom in ammonia is roughly $\ce {sp^3}$ hybridized and the 4 orbitals emanating from nitrogen (the …

Both NH3 and H2O are sp3 hybridised, so the bond angle should be 109.5∘. But NH3 has one lone pair and water has two lones pairs.

We can explain why the bond angle of $\ce {NF3}$ (102°29') is lesser than $\ce {NH3}$ (107°48') by the VSEPR theory, since lone pair lone pair repulsion is greater than lone pair bond pair repulsion.

On increases the number of lone pairs of electrons, bond angle decreases. Therefore, the order of bond angle is N H + 4> N H 3>N H 2− Was this answer helpful?

So, the bond angle in NH 3 is less than 109.5 ∘ which is about 107 ∘ . As water has two lone pairs the bond angle is further reduced to 104.5 ∘ Bond angles in NH 3 and H 2O are 107 ∘ and 104.5 ∘

Dec 29, 2016 · Hydrogen, with its said electronegativity of 2.2 does a fairly decent job of pulling the N-H electron bond pairs towards it. As you would know, adjacent electron bond pairs repel, and it's this …

Jul 10, 2015 · I noticed the fact that all the hydrides of the elements belonging to group IV has bond angle 109.5° while in group V it varies from 107.3° for $\ce {NH3}$ to 91.3° for $\ce {SbH3}$.

The electrons in N H 3 come closer to nitrogen and due to this electrons tries to repel each other. This leads to increase in bond angles of N H 3.

Oct 9, 2018 · This leads to increase in the bond angle of NH3 but in NF3 the bond pairs attract to the Fluorine atom, (terminal atoms). The distance b/w electron pairs increase and hence, repulsion …
