(a)
Interpretation:
Interpret the name of CaH2 is calcium hydride or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(b)
Interpretation:
Interpret the name of PbCl2 is lead (iv) chloride or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(c)
Interpretation:
Interpret the name of CrI3 is chromium (iii) iodide or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(d)
Interpretation:
Interpret the name of Na2 S is disodium sulfide or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
(e)
Interpretation:
Interpret the name of CuBr2 is cupric bromide or not.
Concept Introduction:
The more the element is electropositive in nature, more it releases electron and thus its oxidation state is denoted by roman numerical after the name of cation.
For example in CuCl2, Cu having + 2 state and thus the name can be written as copper (ii) chloride.
Hence, charge of element is written as number of charge denoted with roman number.
