Answer to Question #152057 in Organic Chemistry for Ajjidde

Question

Which molecule contain both covalent and ionic bonds ?
NaCl,NH4OH,CH3OH,MgCO3

Answer 1

In NaCl, Na acts as cation and Cl acts as anion. There is completely ionic bond between them.

But in NH₄OH, there is an ionic bond between NH₄⁺ cation and OH^- anion. Also NH₄⁺ contains 3 covalent bonds between N and three H atoms.

In CH₃OH, all bonds i.e C-H, C-O and O-H bonds are covalent bonds.

In MgCO_{3 ,} Mg is cation and CO₃^2- is anion and there is an ionic bond between them. In CO₃^2- covalent bonds are present among three O atom and C atom.

Hence in this sence, NH₄OH and MgCO₃ both contain both ionic and covalent bonds.
