What is Cannizzaro reaction? Aldehydes that do not have an alpha hydrogen atom undergo auto-oxidation reduction reactions when heated with concentrated or 50% NaOH or KOH solutions.   That is, half of the participating aldehydes molecules are oxidized to carboxylic acids (as sodium or potassium salt)...

 Which is more covalent, AgCl, NaCl, LiCl or KCl?   In the above compounds, Cl– anion is common for all, but cations are different. According to Fajan’s rule, the covalent character in ionic compounds depends on the size of cation, anion and charge of both the cation and anion. Now, the cation with smaller...

 Why is Cu2+ ion more stable than Cu+ ion in aqueous solution?   Many Cu+ compounds are not stable in aqueous solution. These compounds undergo disproportionation reactions to form metallic copper and Cu2+ compounds. &nb...

 Why is phenol more acidic than aliphatic alcohols?   Phenol is acidic in nature. Because of phenol can donate proton in aqueous solution. Although, phenol is weakly acidic but phenol is more acidic than aliphatic alcohols.   The strength of acid depends on the tendency of donating proton in aqueous...

 Why do polar solvent and weak nucleophiles favor SN1 reaction?   Polar protic solvents, such as CH3OH, CH3CH2-OH, H2O, etc., are suitable for SN1 reactions. This is because in this type of solvent, both carbocation and halide anion gain stability. That is, polar protic solvent favor SN1 reaction mechanism...

 Why do nucleophiles always attack from backside in SN2 reactions?   The SN2 reaction occurs in one step through the backside attack. That is, in this reaction, the nucleophile attacks the carbon atom of the substrate from the opposite side of the living group.   The SN2 reaction is completed through...

  What is carbon disulfide?   Carbon disulfide is also known as carbon bisulfide, is a neurotoxic colorless volatile liquid with chemical formula, CS2. The IUPAC name of carbon disulfide is methane dithione.   Carbon disulfide is a colorless liquid in purest form and it is light yellow under impure...

  What is carbon black?   Carbon black material is also known as acetylene black, channel black, furnace black, lamp black, and thermal black. It is a black solid with molar mass 12.01 g/mol. The density of carbon black at 20°C is 1.8-2.1 g/cc.  ...

What is sodium hydrogen carbonate? Sodium hydrogen carbonate is also name as sodium bicarbonate, is a chemical compound with molecular formula, NaHCO3. It is also known as an acidic salt or bi salt, which is made from carbonic acid...

 What is catenation property of carbon?   Catenation property is found in organic as well as in inorganic compounds. The catenation property mainly shows carbon element in organic chemistry.      When two or more atoms of an element combine with each other through the covalently single bond,...

 What is chiral center or stereogenic center? Optical isomerism: The isomerism in which two or more compounds have same physical and chemical properties but they have different behavior towards plane polarized light, are known as optical isomerism and such type of compounds are known as optically active compounds. Chiral centers: When...

 What is ammonia water in inorganic chemistry?   Ammonia water means aqueoussolution of ammonia. Ammonia water is also known as ammonia liquor, aqueous ammonia, ammonium hydroxide, aqua ammonia, ammoniacal liquor etc. It is symbolically expressed as NH3 (aq.) or NH4OH. Ammonia water solution has fishy and...
