Yes, in phenyl hydrazine the electron pair on terminal nitrogen is always available for attack while in analine the electron pair of nitrogen is less available due to involvement in resonance process with benzene ring.

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
Why cyclohexyl amine is stronger than aniline?
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.
Mechanism for the osazone formation of glucose?
After correcting the spelling of the Question Here is the answer for it.Osazones are a class of carbohydrate derivatives formed when sugars are reacted with phenylhydrazine. The reaction involves the formation of a pair of phenylhydrazone functionalities, concomitant with the oxidation of the hydroxymethylene group adjacent to the formyl center. The reaction can be used to identify monosaccharides. It involves two reactions. Firstly glucose with phenylhydrazine gives us glucosephenylhydrazone by the elimination of a water molecule from the functional group.The next step involves reaction of one mole of glucosephenylhydrazone with two moles of phenylhydrazine (excess). First, phenylhydrazine is involved in oxidizing the alpha carbon to a carbonyl group, and the second phenylhydrazine involves removal of one water molecule with the formyl group of that oxidized carbon and forming the similar carbon-nitrogen bond. The alpha carbon is attacked here because it is more reactive than the others.They are highly colored and crystalline compounds and can be easily detected. Glucose gives broomstick shaped crystals with this whereas maltose gives sunflower shaped crystals.
Who is better than all the rest?
Pauls the best... better than all the rest
Is nickel a better conductor than copper?
No - copper is a better conductor than nickel.
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 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.
What is aniline leather?
Semi-aniline leather is more durable than aniline whilst still retaining a natural appearance. The increased durability is provided by the application of a light surface coating which contains a small amount of pigment. This ensures consistent colour and imparts some stain resistance.

Why is it that aniline has a high boiling point to phenol and phenol has a high boiling point than toluene and toluene has a high boiling point than benzene?
It s the structure and bonding of Aniline, Phenol, Benzene and Toluene that causes the differences in the boiling points.
