Alkyl groups are slightly electron donating. The methyl groups on the amine in N,N dimethylaniline contribute electron density to the nitrogen lone pair, making it more likely to reach out and grab a proton (ie more basic).
Hydrazine is more basic than ammonia because it has two amino groups compared to just one in ammonia. This allows hydrazine to donate more protons, enhancing its basicity. Additionally, the lone pair of electrons on each nitrogen in hydrazine is more readily available for accepting protons, making it a stronger base than ammonia.
Neon, ammonia, methane, hydrogen, helium and water vapour are the best lifting gases and are all less denser than air.
No, ammonia is denser than air. The density of ammonia is approximately 0.73 kg/m^3 at standard temperature and pressure, while the density of dry air is about 1.2 kg/m^3. This means that ammonia will tend to sink and accumulate at lower levels compared to air.
Because methyl is an electron pumping group and It pumps electrons to Amine group to make it basic, But Ammonia has no influence from any basic groups. Therefore compared to Methyl-Amine, Ammonia is less basic
Yes, ammonia (NH3) is considered a greenhouse gas. While it is less potent than gases like carbon dioxide or methane, it can still contribute to the greenhouse effect and global warming when present in the atmosphere.
Aniline is less basic than ammonia because the nitrogen lone pair on aniline is partially delocalized into the benzene ring, making it less available to accept a proton. Ammonia, on the other hand, has a more localized lone pair on nitrogen, which is more readily available for protonation.
Because the electron withdrawing resonance efect caused by the nitro group on the structure, it makes the electrons pair on the nitrogen less available, if the electron pair is less available it's less basic
Strength of bases is related to the ease of accepting a proton which inturn depends on the availability of electron pair on the nitrogen atom (or some other basic atom). More is the availability of electron pair, more easily the proton will be accepted and more will be the basic strength.Aniline is a weaker base than ammonia or cyclohexylamine. It is because of the fact that the electron pair on nitrogen is involved in delocalization, making it less available for donation.
Aniline is a weaker base than ammonia because the lone pair on the nitrogen atom in aniline is partially delocalized into the benzene ring, making it less available for donation to form a bond with a proton. In contrast, the lone pair on the nitrogen atom in ammonia is more readily available for donation, resulting in a stronger basicity.
Ammonia is a stronger base than aniline because the lone pair on the nitrogen in ammonia is more readily available for donation compared to the nitrogen in aniline, which is partially delocalized due to resonance. As a result, ammonia is able to more effectively accept a proton to form its conjugate acid, making it a stronger base.
Ammonia is less basic than ethylamine because the lone pair of electrons on the nitrogen atom in ammonia is delocalized in the sp3 orbital, making it less available for donation. In contrast, in ethylamine, the lone pair is in an sp3 orbital on nitrogen, making it more available for donation, resulting in higher basicity.
Because in Benzylamine : the unshared lone pair of electron on nitrogen atom isavailable >.. But in n-ethyl aniline: the unshared lone pair of electron is not available and enter resonance with benzene ring .(Villa)
In o-aniline phenol Intramolecular hydrogen bonding occurs which is not possible in meta and is responsible for less solubility
aniline is more acidic because in aniline a electron withdrawing benzene is connected.electron withdrawing capacity of benzene is due to its delocalizing pi electrons cloud.due the action of benzene the presence of unshared pair of electron over nitrogen is somehow decreases.which increases its acidic nature. But in case of ammonia there is no electron withdrawing group.so its unshared pair of electron remains undistrubed,which decreases its acidity and increases its basisity
Pyridine is more basic than aniline primarily due to the presence of the nitrogen atom in a sp² hybridized aromatic ring in pyridine, which allows it to donate its lone pair of electrons more effectively. In contrast, aniline's nitrogen is part of an amine group attached to a benzene ring, where the lone pair is partially delocalized into the aromatic system, making it less available for protonation. This delocalization in aniline reduces its basicity compared to the more localized lone pair on the nitrogen in pyridine.
Ammonia is less dense than air at room temperature and pressure. This is why ammonia gas rises in air.
Aniline is more basic than p-nitroaniline because the presence of a nitro group (-NO2) in p-nitroaniline decreases its basicity by withdrawing electron density from the amino group. Aniline, on the other hand, lacks this electron-withdrawing group, making it more basic.
