What is muta rotation ?

Posted by Shivani .. 7 years, 1 month ago

CBSE > Class 12 > Chemistry

1 answers

Yogita Ingle 7 years, 1 month ago

Mutarotation is the change in the optical rotation that occurs by epimerization (that is the change in the equilibrium between two epimers, when the corresponding stereocentersinterconverted). Cyclic sugars show mutarotation as α and β anomeric forms are interconvert. The optical rotation of the solution depends on the optical rotation of each anomer and their ratio in the solution.

What is valance bond theory?

Posted by Harsh Choudhary 7 years, 1 month ago

CBSE > Class 12 > Chemistry

2 answers

Yogita Ingle 7 years, 1 month ago

Valence bond theory:

Assumptions of valence bond theory:

(i) It does not give quantitative interpretation of magnetic data.

(ii) It does not explain the colour exhibited by coordination compounds.

(iii) It does not give a quantitative interpretation of the thermodynamic or kinetic stabilities of coordination compounds.

(iv) It does not make exact predictions regarding the tetrahedral and square planar structures of 4-coordinate complexes.

(v) It does not distinguish between weak and strong ligands.

According to this theory, the metal atom or ion under the influence of ligands can use its (n − 1)d, ns, np or ns, np or nd orbitals for hybridisation to yield a set of equivalent orbitals of definite geometry such as octahedral, tetrahedral and square planar.
