What type of bonding is nitric acid?
Nitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate.
Why no bond is shorter than Noh bond in HNO3?
Due to resonance shown above, N-O bond length is average of single bond and double bond whereas N-OH bond has purely single bond character. Therefore, N-O bond is shorter than N-OH bond in HNO3.
Why are the bond lengths for the no bonds in the nitrate ion identical while there are two different bond no bond lengths in nitric acid HNO3?
Re: Lewis Structure for NO3- I agree with 705 and Clarissa that the reason that the bond lengths are the same is because of the resonance structures. This is due to the delocalization of electrons, creating a single-double bond hybrid, so all the bond lengths are actually the same.
In which species NO2 or NO3 -) are the no bond’s longer?
There are more such pairs in NO3− than in NO2−. These pairs tend to repel each other and the bonding pairs, and NO3− requires more room, thus longer bonds, to accommodate the greater number of closely packed nonbonding electron pairs.
Is HBr ionic or covalent?
Therefore the HBr gas has a covalent bond polarized and the hydrogen atom has a slight positive charge and Br has a slight negative charge. In fact, the molecular orbital is attracted toward the bromine.
What is the shape of nitric acid?
planar
The shape of Nitric acid molecule is planar, with the nitrogen atom attached to three oxygen atoms, one of which holds the proton. Other two N-O bonds are equivalent and show the resonance with double bond character.
Why no bond in no2 is shorter than no bond in no3?
The N-O bond in NO_(2)^(-) is shorter than N-O bond in NO_(3)^(-). Account for this observation. while NO-3 is a resonance hybrid of three structures, III, IV and V. ∴ In NO-2 bond order of N-O bond is 3//2=1.5 since it has one duoble bond and one single bond, i.e., three bonds are shared between two O atoms.
How many types of no bond length are present in HNO3?
– Nitric acid has one N=0 bond, one N-OH bond & one N-O bond. – Usually pi-bonds are shorter than sigma-bonds.
How do you know which bond is shorter?
Bond Length The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms and the shorter the bond length.
Which of the following molecule contains shortest No bond?
NO2 – has shortest N-O bond. It has one negative charge which makes two resonating structures.
Which of the following molecule contains shortest NO bond?
Which of the following species has smallest NO bond length?
NO, NO^(+), NO^(2+),NO^(-) Thus , NO+ has the highest bond order and , therefore, the shortest bond length .
What is the structure of nitnitric acid?
Nitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate.
What is the hybridization of HNO3 in nitric acid?
Nitrogen has a steric number of 3, while the oxygen atom in the OH ion has a steric number of 4. The N atom in HNO3 has SP2 hybridization, and the O atom has SP3 hybridization. So, before bonding, nitric acid has 13 (3 + 4 + 2*3) hybrid orbitals, but after the bonding, you can see only six hybrid orbitals.
What type of bond does nitrogen and oxygen form?
One oxygen atom and the OH ion are connected with single bonds respectively while the remaining oxygen atom is connected to nitrogen via a double bond to follow Octet’s rule. In this way, the nitrogen atom attains a stable configuration of eight electrons. It forms a double and a single bond with two oxygen atoms while a single bond with an OH ion.
What is the name of the compound HNO3?
Nitric acid is a nitrogen oxoacid of formula HNO3 in which the nitrogen atom is bonded to a hydroxy group and by equivalent bonds to the remaining two oxygen atoms. It has a role as a protic solvent and a reagent. It is a conjugate acid of a nitrate. Nitric acid (HNO3).
