Which of the following statements are incorrect about the oxidation state and acidic nature of oxo-acids?

Correct Answer - C The acidic nature of carboxylic acids is due to greater reasonacne stabilisatio of the carboxylate ion over carboxylic acid.

Correct Answer - B::C (a) Cerium (Z = 57) implies Electronic configuration = `[Xe]4f^(5)5d^(0)6s^(2)` Oxidation state of Ce = +3, +4 (b) Europium (Z = 63) implies Electronic configuration = `[Xe]4f^(7)5d^(0)6s^(2)`...

Correct Answer - B::C Electronic configuration of `._(58)Ce = ._(54)[Xe]4f^(2)5d^(0)6s^(2)`. Therefore, electronic configuration of `Ce^(4+)=._(54)[Xe]4f^(0)`. Thus, it has a tendency to attain noble gas configuration and attain `f^(0)` configuration.

Correct Answer - A M=0 bonds are called oxo bonds in organic compounds `H_(2)SO_(4)` has two S=O bonds, where as `H_(2)SO_(3)` has one S=O bond. `H_3PO_(3)` has one P=O and `H_(3)PO_(4)`...

Correct Answer - D The acidity of oxo acid of the same. halogen increases with the increase in oxidation state the halogen. It is because the release of `H^(+)` in each...

Correct Answer - A As the oxidation state of halogen atom increases, the halogen-xoygen bond becomes more covalent. As a result, thermal stability of the acid increases and hence, oxidizing power...

Correct Answer - B We know that, +3 oxidation is common in all series. Stable of +3 O.S. depends upon high hydration energy, high lactic energy and high I.P. `Nd^(2+)` -...

Correct Answer - B In oxo process alkenes are converted into aldehydes (with one carbon atom more) by treating alkene with CO and `H_(2)` in the presence of `[Co(CO)_(4)]_(2)` at high...

(i) `Cr_(2)O_(7)^(2-)` ion (ii) Cerium (Ce).

(i) In acidic amino acids, carboxyl groups are than the amino group. In basic amino groups are more as compared to carboxyl groups. (ii) The linkage is known as phosphodiester...
