Answer:
The nitration of phenol is easier than that of benzene because benzene has delocalised pie-electrons which makes it more stable than phenol.
Phenol is converted to Trinitrotoluene by adding zinc dust to remove the hydroxyl group, then reacted with Aluminium oxide followed by haloalkane.
Answer:
0.05 g of H2O contain molecules
Answer:
Ba -> Ba2+ + 2e-
Explanation:
A neutral atom becomes an iron when that atom loses electrons. The number of electroms lost by that atom determines the ionic charge or charge of it's ion. In this case, a neutral Barium atom (Ba) will become a barium ion, which has a charge of +2, when it loses 2 electrons to a more electronegative atom in a reaction.
The equation is:
Ba -> Ba2+ + 2e-
2e- is the two electrons lost
The amino acids are the molecules where we can found the carboxyl group (-
), amino group (-
), hydrogen atom (H) and a residual R-group. On the structure of the residual R-group the name of the amino acid depends. Like if R is hydrogen (H) the amino acid is alanine; If R- group is a phenyl group i.e. 
, the compound is called phenyl alanine. The structure of the general amino acid skeleton can be shown as-
