in the case of aniline, the lone pair on nitrogen is involved in resonance with the benzene ring, hence its basicity decreases. no such resonance is seen in cyclohexyl amine, and the lone pair is available to abstract protons and it is stronger base than aniline.

Why is o-aniline phenol less soluble in water than m-aniline phenol?
In o-aniline phenol Intramolecular hydrogen bonding occurs which is not possible in meta and is responsible for less solubility
Is the main reason for your amine to be loaded up with H2S Co2 the low temperature or is it that the percentage of amine is higher then normal 50 50?
To me both reason can incresed acid gas loading in lean amine. 1.When lean amine temperature is low then then amine absorb more quantity of H2S,CO2 which result high acid gas loading in lean amine. 2.When amine solution concentration is hiegher than 50/50 then slow absorption of CO2 but H2S absorption incresed which result high acis gas loading in lean amine. Note: Lean amne temperature is the main thing to increase acid gas loading. Jan Muhammad My take is that if your amine titration is higher than 50%, and are having trouble with loadings, then you are probably running out of regeneration (still/reboiler). It is critical to maintain a good overhead temperature and reboiler temperature so that the amine can be regenerated. Proper titration and lean amine temps tie back into this...
Is Jupiter stronger or weaker than earth gravity?
It is stronger.
Is water stronger than lava?
lava is stronger
Are humans stronger than cougars?
No, the cougar is much stronger than an average human.
Dimethyl amine is stronger base than methyl amine?
How am I suppose to know huh
Which is more basic cyclohexyl aniline or aniline?
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.
Why aniline is weaker base than methylamine?
Since tha pka of the aniline ion is equal to 4.6, the anilinium ion is a stronger acid than the methylaminium ion, and aniline (c6h5nh2) is a weaker base than methylamine (ch3nh2).
Why cyclohexylamine is a stronger base than aniline?
aniline is weaker base because it is stabilized by resonance leaving less negative charge to hold the proton.
Why ammonia is stronger base than aniline?
The lone pair on the nitrogen of aniline is delocalised into the pi-system of the benzene ring and is therefore less available for attack on a proton.
Why the amino group of p-aminobenzoic acid does not participate in the synthesis of benzocaine?
Its because its an aniline and that is less electrophilic than an alkyl amine thats also there so that will be used instead.
Why is aliphatic amines stronger bases than aromatic amines?
because aromatic amines are stronger acid due to its being a secondary amine
Why is aniline weak base?
The amine lone pair in aniline is conjugated to the benzene ring. Amines are strongly electron donating, so the lone pair is partially "stuck" in the aromatic system. This means that it is less available to latch onto a proton (the definition of basicity).
Why dipole moment of chlorobenzene is lower than that of cyclohexyl chloride?
In chlorobenzene, the chlorine atom is attached to hybridized carbon atom(more 's' character). In cyclohexyl chloride, the chlorine atom is attached to hybridized carbon atom (less's' character than hybridized carbon atom). Hence chlorobenzene is more electronegative than cyclohexyl chloride. Therefore, the density of electrons C-Cl bond at chlorine atom is less in chlorobenzene than cyclohexyl chloride.The density of electrons C-Cl bond at chlorine atom in chlorobenzene decreases due to the -R effect of the benzene ring which is not in cyclohexyl chloride. Due to this polarity of the C-Cl bond decreases and hence dipole moment of chlorobenzene is lower than cyclohexyl chloride.
Is Aniline heavier than water?
Yes aniline is heavier than water.Answer:Aniline i slightly denser than water. An equal volume of aniline will have about 2% more mass than water.
Why benzyl amine is more basic than n-ethyl aniline?
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)
Which is strong base aniline or o-nitroaniline?
Dyes are of several types they may be acidic , basic or neutral, organic dyes are mostly basic.
