Which of the following indicate the correct variation of electronegativity?

Correct answer: D. F > O > N > C

  • A. F > N > O < C
  • B. F > N > O > C
  • C. F< N < O < C
  • D. F > O > N > C

Explanation

The relative tendency of a bonded atom in a molecule to attract the shared electron pair towards itself is called electronegativity. The positively charged protons in the nucleus attract the negatively charged electrons. As the number of protons in the nucleus increases, the electronegativity or attraction will increase. Therefore electronegativity increases from left to right in a row in the periodic table. Here, the correct order of electronegativity is: F > O > N > C

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.
