The percentage of co-ordinate covalent bond present in BF4- and NH4+ respectively

Correct answer: D. 25% cach

  • A. 25% and 33%
  • B. 33% cach
  • C. 33% and 25%
  • D. 25% cach

Explanation

BF4- and NH4+ both have 3 covalent bonds and 1 co-ordinate covalent bond in their structure. Hence out of total 4 bonds 1 is co-ordinate covalent and cach bond have 25% co-ordinate covalent character. (%age of dative bond = 1×100/4 = 25%)

About Chemical Bonding

Chemical bonding explains molecular shape through VSEPR theory and distinguishes sigma bonds from pi bonds. Questions involve hybridization, bond angles, dipole moment and bond energy, including how electron-pair repulsion determines geometry and how bond polarity differs from the overall polarity of a molecule.
