Question

When naming and writing molecular formulas do you use the prefixes and when you name ionic compounds and formulas you write the formula based off of their ion charges?

Answer 1

A:- Naming Organic Compounds:

                                                 Yes, if the organic compounds has twwo different functional groups, the name of main (first grade) fuctional group is written in 2⁰ suffix, second grade fuctional group is written in 2⁰ prefix.

Example: 2-hydroxy propanal (CH₃CHOHCHO)

Naming of Ionic Compounds:

                                       In the case ionic copounds, we just write formula of ionic compounds to balance their charges, no need to write their oxidation states.

Example: AlCl₃ (Aluminium chloride), Pb(NO₃)₂ (lead nitrate).

In the case of coordination compounds we have to write the oxidation state of metal ion in numerical letters within a braket

Example: [Co(NO₂)₃(NH₃)₃] => Triamminetrinitrocobalt(III). => III is the oxidation state of Co metal ion.
