Answer :

(a) The name for [tex]NaF[/tex] is sodium fluoride.

(b) The name for [tex]Rb_2O[/tex] is rubidium oxide.

(c) The name for [tex]BCl_3[/tex] is boron trichloride.

(d) The name for [tex]H_2Se[/tex] is dihydrogen selenide.

(e) The name for [tex]P_4O_6[/tex] is tetraphosphorous hexaoxide.

(f) The name for [tex]ICl_3[/tex] is iodine trichloride.

Explanation :

The nomenclature of covalent compound is given by:

1. The less electronegative element is written first.

2. The more electronegative element is written then, and a suffix is added with it. The suffix added is '-ide'.

3. If atoms of an element is greater than 1, then prefixes are added which are 'mono' for 1 atom, 'di' for 2 atoms, 'tri' for 3 atoms and so on..

The nomenclature of ionic compounds is given by:

1. Positive ion is written first.

2. The negative ion is written next and a suffix is added at the end of the negative ion. The suffix written is '-ide'.

3. In case of transition metals, the oxidation state are written in roman numerals in bracket in front of positive ions.

(a) [tex]NaF[/tex] is an ionic compound because sodium element is a metal and fluorine element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

So, the name for [tex]NaF[/tex] is sodium fluoride.

(b) [tex]Rb_2O[/tex] is an ionic compound because rubidium element is a metal and oxygen element is a non-metal. The bond formed between a metal and a non-metal is always ionic in nature.

So, the name for [tex]Rb_2O[/tex] is rubidium oxide.

(c) [tex]BCl_3[/tex] is a covalent compound because boron and chlorine element is a non-metal. The bond formed between the non-metal is always covalent in nature.

So, the name for [tex]BCl_3[/tex] is boron trichloride.

(d) [tex]H_2Se[/tex] is a covalent compound because hydrogen and selenium element is a non-metal. The bond formed between the non-metal is always covalent in nature.

So, the name for [tex]H_2Se[/tex] is dihydrogen selenide.

(e) [tex]P_4O_6[/tex] is a covalent compound because phosphorous and oxygen element is a non-metal. The bond formed between the non-metal is always covalent in nature.

So, the name for [tex]P_4O_6[/tex] is tetraphosphorous hexaoxide.

(f) [tex]ICl_3[/tex] is a covalent compound because iodine and chlorine element is a non-metal. The bond formed between the non-metal is always covalent in nature.

So, the name for [tex]ICl_3[/tex] is iodine trichloride.
