Ortho para percentage is not to be learned. To determine the major product among ortho , meta ,and para we classify groups as ortho ,para or meta directing . You should be able to find their list on the web ,among groups which are ortho and para directing ( both simultaneously) the para productnis major in most cases except when methyl substituted benzene

Difference between stoichometric and non stoichometric defect

Posted by Nandini Virk 7 years, 7 months ago

CBSE > Class 12 > Chemistry

1 answers

Lekha Raj 7 years, 7 months ago

In stoichometric defect,the formula of the compound remains same .But in non-stichometric defect ,the standard formula or the ratio in which the various elements are present changes.For example,ZnS shows Frenkel defect but it's formula does not changes but FeO shows metal dificiency defect which causes in it's non -stoichometry ie Fe0.93O.
