HVZ reaction:

Higher the value of K_a more is the acidic strength.

Cannizzaro reaction is shown by aldehydes containing no a–H atoms

In heterolytic bond cleavage ions are formed. hence for ionic reaction in organic compound heterolytic bond cleavage takes place.

Zn²⁺ has no unpaired electron and colourless in aqueous solution.

Homoleptic complexes in which a metal is bound to only one kind of donor groups/ligands.

International students who desire to study MBA in Poland, English language requirement is an important admission requirement for these students. Universities in Norway accepts English proficiency scores as proof. Students can refer to the table below to know more about minimum score details:

Due to inert pair effect Tl shows +1 oxidation state.

In aniline –NH₂ is strong activating group due to presence of lone pair in nitrogen.

Aniline does not show Friedel-Craft alkylation reaction, because anhydrous AlCl₃ and aniline form salt together

Potassium hydrogen phthalate is used to standardize NaOH solutions.

Phenolphthalein is used as an indicator to detect completion of titrations.

Suspension of slaked lime in water is known as milk of lime

Crude sodium chloride obtained by crystallisation of brine solution contains CaSO₄, Na₂SO₄ and MgCl₂

Beryllium salts are easily hydrolysed

Gypsum : CaSO₄ * 2H₂O

PbS + 4H₂O_2->PbSO₄ + 4H₂O.

Work depends on the path followed by the system so work is path function.

[Ni (H₂O)₆]²⁺ Þ Ni²⁺ is octahedral and [Ni (CN)₄]^2– is square planar.

In [Ni (H₂O)₆]²⁺ Þ Ni²⁺ has two unpaired electrons and in [Ni (CN)₄]^2– Þ Ni²⁺ has no unpaired electrons. [Ni (H₂O)₆]²⁺ is coloured as it absorbs red light due to suitable d-d transition and complementary light emitted is green.

[Ni (CN)₄]^2– has strong field ligand so the electrons of Ni²⁺ pair up and it is colourless as it cannot absorb light from visible region.

Since V_Real > V_ideal

So, Z = V_Real > 1. V_ideal
