What is the shape of NH2?
What is the shape of NH2?
If the amine group (NH2) is part of a molecule it will be pyramidal in structure. Ammonia, NH3 is based on a tetrahedron with bond angles of 107 (reduced from 109.5 degrees to 107 degrees on account of the lone pair-bond pair repulsion), with the resulting shape being pyramidal.
Is NH3 sp2 or sp3?
In Ammonia (NH3) or to be more precise the central atom in ammonia which is nitrogen is sp3 hybridized.
What is the geometry of NH2 minus?
Nh2 negative is linear or angular in shape.
What is the hybridization of NH2 negative?
C = Charge of the cation. A = Charge of the anion. Therefore, the hybridization of NH−2 is sp3 and has the shape bent or angular . Thus, the correct option is (b).
What is the Lewis structure of NH2?
Six, and eight. At this point to the hydrogens have 2 valence electrons so their outer shell is full and nitrogen needs an octet. It has eight valence electrons so its octet is full. So this is the Lewis structure for NH2-.

What functional group is NH2?
amino group
Is NH a functional group?
In organic chemistry, the most common functional groups are carbonyls (C=O), alcohols (-OH), carboxylic acids (CO2H), esters (CO2R), and amines (NH2). It is important to be able to recognize the functional groups and the physical and chemical properties that they afford compounds.
Is NH2 an R group?
Each amino acid contains a central C atom, an amino group (NH2), a carboxyl group (COOH), and a specific R group. Peptide bonds form between the carboxyl group of one amino acid and the amino group of another through dehydration synthesis. A chain of amino acids is a polypeptide.
Is Nitro a functional group?
The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally. The nitro group is also strongly electron-withdrawing. Because of this property, C−H bonds alpha (adjacent) to the nitro group can be acidic.
Why is nitro group explosive?
Nitro compounds are explosive because although the diatomic form of nitrogen is very stable – that is, the triple bond that holds N2 together is very strong, and therefore has a great deal of bond energy – the nitro compounds themselves are unstable, as the bonds between nitrogen atoms and other atoms in nitro …
What is the highest priority functional group?
Carboxylic Acids
What is the structure of Nitro?
Nitro compound, any of a family of chemical compounds in which the nitro group (―O―N=O) forms part of the molecular structure. The most common examples are organic substances in which a carbon atom is linked by a covalent bond to the nitrogen atom of the nitro group.
What are nitro alkanes?
Nitroalkanes react with either carbonyl compounds (Henry reaction) or imines (aza-Henry reaction) to produce β-hydroxy-nitro compounds or β-amino-nitro compounds, respectively, under mild conditions.
Is Nitro meta directing?
2: Thus, the nitro group is a meta directing group. Ortho, para directing groups are electron-donating groups; meta directing groups are electron-withdrawing groups. The halide ions, which are electron-withdrawing but ortho, para directing, are the exception….
Is nitrobenzene acidic or basic?
nitro group is a strong withdrawing group and deactivating also so the positive charge on the benzene increases….if the positive charge increases the acidic nature increases…. therefore nitrobenzene is more acidic than benzene…….
Is aniline an acid or base?
Methyl amine, , is similar in strength to ammonia; phenyl amine or aniline, , is a weak base with a of only 4.63.
Which is more basic phenol or aniline?
Aniline is more basic. Phenol loses a proton easily to form the phenolate ion, and therefore is a reasonably stong acid. Aniline only reluctantly accepts a proton to form the anilinium ion, and hence is a weak base.
What is Nitrating mixture?
a mixture of concentrated nitric acid or nitrogen oxides with inorganic compounds (H2SO4, BF3, and AlCl3) or organic compounds (for example, acetic anhydride). It generates the active nitrating species NO2+ (the nitronium cation):
Why H2SO4 is used in nitration?
In the protonation of nitric acid by sulfuric acid, the source of the nitronium ion induces the removal of a water molecule and the creation of a nitronium ion. The first step in benzene nitration is to activate HNO3 with sulfuric acid to create a nitronium ion, a stronger electrophile.
What is the purpose of nitration?
Nitration is used to add nitrogen to a benzene ring, which can be used further in substitution reactions. The nitro group acts as a ring deactivator. Having nitrogen present in a ring is very useful because it can be used as a directing group as well as a masked amino group….
What is the role of H2SO4?
In esterification reactions, concentrated H2SO4 (sulfuric acid) is known to be used as a catalyst. Here, the sulfuric acid plays a dual role – it works to speed up the rate of the reaction while simultaneously acting as a dehydrating agent, thereby forcing the equilibrium reaction to the right.
What conditions are used for nitration?
Nitration happens when one (or more) of the hydrogen atoms on the benzene ring is replaced by a nitro group, NO2. Benzene is treated with a mixture of concentrated nitric acid and concentrated sulfuric acid at a temperature not exceeding 50°C….
How does sulfuric acid catalyzed esterification reaction?
Esterification Reaction An acid catalyst, typically in the form of sulfuric acid, is added to increase the rate of the reaction while also acting as a dehydrating agent. The mechanism of action for a Fisher esterification begins by the carbonyl oxygen attacking the sulfuric acid and deprotonating its OH group.
What is the concentration of H2SO4?
Dilutions to Make a 1 Molar Solution
| Concentrated Reagents | Density | Molarity (M) |

How do you calculate percent purity of HCL?
35.453+1.g/mol . 1.18 gmL ⋅1000mL 1 L ⋅1 L =1180 g . Thus, 35% w/w for HCl puts it at 413 g HCl1180 g soln ….
What is the strength of concentrated HCL?
Hydrochloric acid is produced in solutions up to 38% HCl (concentrated grade).
Is H2SO4 a strong acid?
Encyclopædia Britannica, Inc. Sulfuric acid is a very strong acid; in aqueous solutions it ionizes completely to form hydronium ions (H3O+) and hydrogen sulfate ions (HSO4−). In dilute solutions the hydrogen sulfate ions also dissociate, forming more hydronium ions and sulfate ions (SO42−).
