Chemical Bonding
Polarisation is the distortion of the shape of anion by an adjacently placed cation. Which of the following statement is correct?
Among the following, the maximum covalent character is shown by which compound?
As the cation charge increases, the covalent character also increases.
According to Fajans rule, cation with greater charge and smaller size favour covalency.
All the central metals have $$+2$$ oxidation except for $$Al$$ which has $$+3$$ oxidation state.
Hence, $$Al$$ shows more covalent character as compared to others.
Polarisation is the distortion of the shape of anion by an adjacently placed cation. Which of the following statement is correct?
Which of the following has been arranged in order of increasing covalent character?
Polarising action of $$Cd^{2+}$$ an anions is stronger than that of $$Ca^{2+}$$ because:
Which compound among the following has more covalent character ?
Amongst $$LiCl$$, $$RbCl$$, $$BeCl_2$$ and $$MgCl_2$$, the compounds with the greatest and the least ionic character, respectively are:
Among the following which one has the highest cation to anion size ratio?
Arrange the below molecules in order of increasing ionic character.$$LiF$$ $$, \ \displaystyle K_{2}O $$, $$ \displaystyle N_{2} $$, $$ \displaystyle SO_{2} $$ and $$ \displaystyle ClF_{3} $$
The correct order of the increasing covalent character of the following is:
The bond length in $$LiF$$ will be:
According to Fajan's rule, covalent bond is favoured by:
