Question

Fill in the blanks

1.$\pi$ bonds are formed by _______overlapping of _______ orbitals.

2.Meso form of tartaric acid is ________ due to _______ compensation.

3.________ and ______ are temperature independent modes of concentration representation

4.In conversion of ${Cl}_2$ to ${ClO}_3^{-}$, the oxidation state of chlorine changes from _______ to _______

Answer 1

Solution:-

(A) $\pi$ bonds are formed by $\underset{–}{\text{sidewise}}$ overlapping of $\underset{–}{\text{p}}$ orbitals.

(B) Meso form of tartaric acid is $\underset{–}{\text{optically inactive}}$ due to $\underset{–}{\text{internal}}$ compensation.

(c) $\underset{–}{\text{Molality}}$ and $\underset{–}{\text{Mole fraction}}$ are temperature independent modes of concentration representation.

(D) In conversion of ${Cl}_2$ to ${Cl{O}_3}^{-}$, the oxidation state of chlorine changes from $\underset{–}{0}$ to $\underset{–}{+5}$.
