17 Organic Chemistry Questions And Answers

2⟩ What is the difference between an ion and a radical?

An ion is a specie that have no unpaired electron and is charged, either positively or negatively i.e. may be a cation or an anion. It is formed due to heterolysis of a molecule e.g HCl----> H+ + Cl-

A radical is a neutral specie having atleast one unpaired electron and is formed due to homolysis of a molecule e.g

H-H -------> H* + H*

The * shows an unpaired electron. Similarly CH3* is a radical.

5⟩ HOW WE CAN DIFFERENTIATE BETWEEN OXALIC ACID AND TARTARIC ACID?

By Fluorescein test ...

where tartaric acid " used in baking powder and found

in many food products

oxalic acid : harmful in contact with skin or eyes

toxic .remove Ca ions From blood and also block Kidneys

Fluorescein test depended on Light passes & usually in UV light

6⟩ Why are you using thioacetamide reagent in heavy metals test?

Thioacetamide is widely used in classical qualitative inorganic analysis as an in situ source for sulfide ions. Thus, treatment of aqueous solutions of many metal cations to a solution of thioacetamide affords the corresponding metal sulfide:

M2+ + CH3C(S)NH2 + H2O ? MS + CH3C(O)NH2 + 2 H+ (M = Ni, Pb, Cd, Hg)

Related precipitations occur for sources of soft trivalent cations (As3+, Sb3+, Bi3+) and monovalent cations (Ag+, Cu+).
