Kindly consider the following Image 

$\Delta T_f=0.5°C$

K_f = 1.86

Using, density of water = 1g / mL

i = ?

$\Delta T_f=i{k}_f.m$           

$0.5=i\times 1.86\times \frac{9.45}{94.5\times 500}\times 1000$          

i = 1.344

Now, using $\alpha =\frac{i-1}{n-1}$  

n for ClCH₂COOH = 2

 a =   $\frac{1.344-1}{2-1}=0.344$

Using

  $K_a=\frac{C{\alpha }^2}{1-\alpha }$           

$K_a=\frac{0.2\times {\left(0.344\right)}^3}{0.66}=36\times 10^{-3}$           

           So; x = 36

If the carbonyl compound is sterically crowded, then it will be reluctant to undergo addition reaction. Moreover, attachment of bulkier alkyl group with the carbonyl carbon decreases the partial positive charge resulting into the minimization of attack by R? from RMgBr. So, the order is

According to Gauss’s law for magnetism, the net magnetic flux through any closed surface is zero.

$?\mathbf{B}\cdot dA=0$

It states that all magnetic field lines must enter and exit from a surface. In this way, it differs from electric charges, which can exist independently as positive and negative.

Kindly consider the following Image 

Here cyclohexanone is formed as follows

Magnetism is the force exerted by a magnet. It comes when the magnet attracts or repulses an object. For example, a magnet sticks to certain objects because the magnetic force or magnetism pulls it.

A (g) -> B (g)        K_P = 100

$\Delta G$ at 300 K and 1 atm

Using

$\Delta G=-RTlnK{}_P$           

$\Delta G=-R\times 300ln100$            

=-R × 300 × 2 × 2.3

$\Delta G=-1380R$            

           So; x = 1380.

Stability constant are :

K₁ = 10⁴

K₂ = 1.58 × 10³

K₃ = 5 × 10²

K₄ = 10²

Overall stability constant K will be

 K = K₁ × K₂ × K₃ × K₄

 = 7.9 × 10¹¹

 Now, overall equilibrium constant for dissociation of [Cu (NH₃)₄]²⁺ is

$K\text{'}=\frac{1}{K}=\frac{1}{7.9\times 10^{11}}=0.126\times 10^{-11}$            

= 1.26 × 10^-12

So; x = 1 (Rounded off to the nearest integer)

Reimer-Tiemann reaction.

Beo & Be (OH)₂ are amphoteric in nature, because they react with both acid and base

The Jadavpur University is ranked 18 by the NIRF in 2025. However, the NIRF rank for other similar institutes is around 20 - 45 ranks which means that the BE courses at Jadavpur University follow a higher level of quality for their course.

Methane gas is produced during anaerobic degradation of vegetation that leads to global warming so considered as greenhouse gas like CO₂. Also it causes cancer.

Base is tert-butoxide thus favours elimination with 3° alkyl halide and gives alkene
