DiBAL-H is electron deficient reducing agent as Burane and readily reduces electron rich sp.

$AgBr?A{g}^{+}+B{r}^{-}$                

S + 10^-7                        S

(S + 10^-7) S = 12 * 10^-14

  $\therefore S=3*10^{-7}M$          

${\kappa }_{totel}=\left[6*4*10^{-7}\right]+\left[8*3*10^{-7}\right]+\left[7*1*10^{-7}\right]$          

= 55 * 10^-7 S m^-1

The slag formed is CaSIO₃ which is lighter and has less melting point.

Ferdal Craft reaction not shown by Highly Activated Rings.

Two same group on any C-atom of double bond ⇒ (compound does not show geometrical isomerism)

Gutta percha is a synthetic rubber and its monomer is isoprene .
Since isoprene has EDG, so it is prepared by cationic addition polymerization

Anode      Ag + Br^- -> AgBr + e^-

Cathode   Ag⁺ + e^- ® Ag

From Reaction

Δn? = 2 – 1 = 1

Kp = Kc (RT)^Δn?

Kp = Kc (RT)¹

Kc = Kp (RT)? ¹

Thermal stability of compound is directly proportional to large anion of s-block elements:

T.S ∝ 1/ (PP of cation)

And p.p. ∝ charge ∝ 1/size, So, [T.S. ∝ size ∝ 1/ (charge)]

So, Sr [NO? ]? is highly stable

But Mg (NO? )? ⇒ poor

All have same molarity, pH ∝ 1/ (Acidic strength) ∝ Basic strength

H? SO? → Acidic

NH? Cl (Salt of weak base and strong acid)

Acidic but less than H? SO?

NaCl → (Neutral solution)

NaOH → Basic (Strong Base)

So NaOH > NaCl > NH? Cl > H? SO?
