Account for :
(i) Amino group in aniline is o- and p- directing in aromatic electrophilic substitution reactions. Aniline on nitration gives a substantial amountb of m-nitroaniline.
(ii) Aniline does not go Friedel Crafts reaction.
(i) It is because aniline is formed by protonation with NH3 i.e., EWG hence it is m-directing i.e., 47%.
(ii) It is because aniline is basic, can form adduct with AlCl3, electrophile cannot be generated.
No. This information is not sufficient to determine which of the traits − blood group A or O − is dominant. This is because we do not know about the...
Titrating a neutral or basic amino acid against a weak base will dissociate only one functional group, whereas titration between acidic amino acid and a weak acid will dissociate two...
A compound is said to be aromatic if it satisfies the following three conditions:
(i) It should have a planar structure.
(ii) The π–electrons of the compound are completely delocalized in the...
Benzene is a planar molecule having delocalized electrons above and below the plane of ring. Hence, it is electron-rich. As a result, it is highly attractive to electron deficient species...
(i) NH2 is ERG, electrophilic substitution takes place faster.
(ii) Nitro compounds are more polar than hydrocarbons therefore have more van der Waals forces of attraction.
Directing refers to the process of instructing, motivating, guiding and leading the people to achieve certain goals and objectives. Directing involves the following four elements.
i. Supervision: Supervision implies the process...
Directing as a function of management is quite complex. To help in the directing process, certain principles have been developed. The following are the principles of directing.
(a) Maximum Individual Contribution: According...
The acidity of nitrophenols (or any acid for that matter) is determined by the stability of the conjugate base. In the case of m-nitrophenol, the relative stability can be determined by...
