As we move down the group in group 13 and 14 the participation of s-electrons in bond formation decreases the primary reason behind this is the inert pair effect.

In this the p-electrons take part in bond formation and more energy is required to unpack the valence electrons to make them participate in bonding. Due to this the lower oxidation state of elements becomes stable done the hire oxidation state. As for group 13, +1 oxidation state is more stable than +3 and for group 14, +2 oxidation state is more stable than +4.

Frictional force f is acting in the opposite direction of F . let the acceleration of centre of mass of disc be a then

F-f=Ma where M is the mass of the disc

$\alpha =\frac{a}{R}$

$\tau =I\alpha$

fR= (1/2 MR²) $\alpha$

so fR= (1/2MR²) (a/R)

Ma=2f

From the above equation

F = F/3

F< $\mu N$ = $\mu Mg$

f/3 < $\mu Mg$

F=3 $\mu Mg$

area of square = area of rectangular plate

C²=a $\times$ b

(a) $\frac{I_{xR}}{I_{xS}}=\frac{b^2}{c^2}$ here bxRxS

(b) $\frac{I_{yR}}{I_{yS}}=\frac{a^2}{c^2}$ here a>c so I_yR>I_yS

(c) I_zR-I_{zS $\propto \left(a^2+b^2-2c^2\right)=a^2+b^2$} +2ab= (a-b)²

(I_zR-I_zS)>0

$\frac{I_{zR}}{I_{zS}}1$

Both BCl₃ and AlCl₃ are electron deficient compounds that are central atom boron and aluminium have incomplete Octet. In each compound, a metal atom is surrounded by six electrons of three covalent bonds with 3 chlorine atoms.

Each chlorine atom has a complete Octet of eight electrons. The electron deficient compounds act as Lewis acid and readily accept two electrons to complete their octet.

H₃BO₃

Boric acid forms a hexagon and rings through hydrogen bonding and has a layer-like structure.

Boric acid is present in water as [B (OH)₄]−.H₃BO₃ electron from the OH of water and forms the complex BOH for negative for sp³ and is present in sp³ hybridisation.

Reaction:

B (OH)₃+2H₂O→ [B (OH)₄]⁻ + H₃O⁺

(a) Situation as given below

(b) F’ =F=F’’ where F’ and F’’ are external forces through support.

So F_net=O

External torque = F $\times 3R$ (anticlockwise)

(c) Let w₁ and w₂ be the final angular velocities of smaller and bigger drum in both clockwise and anticlockwise . finally there will be no friction

hence Rw₁=2Rw₂

so $\frac{w_1}{w_2}=2$
