Identify the different types of bonds present in quaternary ammonium salts.

Options

  1. ACovalent
  2. BIonic
  3. CCovalent and co-ordinate
  4. Dcovalent, co-ordinate and ionic

Correct answer

D. covalent, co-ordinate and ionic

Step-by-step solution

Quaternary ammonium salts have the general formula R₄N^+ X^- . The bonds present within the alkyl or aryl groups ( R ) and three of the nitrogen-carbon bonds are covalent. The fourth nitrogen-carbon bond is formed by the donation of the lone pair of electrons from the nitrogen atom to an electron-deficient carbon atom, which is a co-ordinate (dative) bond. The electrostatic force of attraction between the complex quaternary ammonium cation ( R₄N^+ ) and the counter anion ( X^- ) constitutes an ionic bond. Thus, qua
