x + 4 * 0 – 2 * 1 = +1

x = +3

Fe⁺³ = 4s⁰ 3d⁵

In presence of strong ligand, i.e, CO.

Spin only magnetic moment

$=\sqrt[]{n\left(n+2\right)}B.M=\sqrt[]{1\left(1+2\right)}B.M$

Electrophilic addition of bromine to an alkene is anti-addition, in which cis-alkene gives two enantiomers and trans – alkene gives meso form

Here; trans-but-2-ene will give meso products

Structure (I) is anti conformer.

Structure (II) is fully eclipsed conformer.

Structure (III) is skew or gauche conformer.

Structure (IV) is partially eclipsed.

$\therefore$ order of stability

(I) > (III) > (IV) > (II)

Order of P.E. is (II) > (IV) > (III) > (I).

Na/H₂ can not reduce a functional group as Na does not behaves as catalyst here.

Stability order of oxides (X₂O) is,

l₂O > Cl₂O > Br₂O

Bonds of halogen & oxygen are covalent due to less EN difference.

Stability of (I - O) bond is higher due to less polarity and that of (Cl-O) bond is higher due to multiple bonding.

(a) Cell constant = $\left(\frac{\mathcal{l}}{A}\right)=m/m^2=m^{-1}$  

(b) molar conductivity $\left({\lambda }_m\right)=\frac{\kappa *1000}{molarity}$

= Scm² mol^-1

(c) Conductivity $\left(\kappa \right)=\frac{1}{\rho }=\frac{\mathcal{l}}{RA}$

$={\Omega }^{-1}{m}^{-1}$                                

(d) degree of dissociation = $\frac{numberofmoledissociated}{Totalmole}$ , it is dimensionless 

Ethylene glycol (HO – CH₂ – CH₂ – OH) and terephthalic acid

Rate constant depends on temperature as

$K=A{e}^{-Ea/RT}$              

Here; as T increases rate constant increases exponentially.
