-amino- -methyl- -phenyl propane

The order of increasing stability of carbocations is

Carbocation is least stable and converts to more stable carbocation through rearrangement.

Electrophiles are electron loving chemical species.
They may be either positively charged or electrically neutral chemical species,
eg, etc.

The neutral or positively charged species with deficiency of electrons and capable of accepting a pair of electrons (Lewis acid) are called electrophiles, e.g., and .

is the most stable redical. Increasing order of their stability is

Kjeldahl method can not be used for compounds having azo groups nitroso azoxy compounds

and nitrogen in the ring (pyridine, quinoline etc.) Since, nitrogen in these compounds is not quantitatively converted into ammonium sulphate.

When an ether solution of benzoic acid aniline and toluene is extracted with aqueous , then the benzoic acid is dissolved in aqueous . Therefore, the ether layer will contain aniline and toluene .

-methyl- -hexanone is not possible due t over valency of carbon.

A liquid which decomposes at or below its boiling points can be purified by distillation under reduced pressure or vaccume distillation e.g., purification of glycerol, etc, concentration of cane sugar juice.

Stability of carbocation depends upon the number of hyperconjugative structures. More the hyperconjugative structure (i.e., more the number of hydrogen atoms attached directly to a-carbon atom), more is the stability of carbocation
Thus, the order of stability of given carbocation is

Thus, is least stable carbocation among the given

is an electrophile, because its octet is not complete to required two more electron to complete its octet.
Out of valence electrons, are shared with -atoms and are with .
carbene present in two form singlet and triplet.
