Among LiCl, BeCl2 BCl3 and CCl4, the covalent bond character follows the order [1990]
  • a)
    LiCl < BeCl2 > BCl3 > CCl4
  • b)
    BeCl2 < BCl3 < CCl4 < LiCl
  • c)
    LiCl < BeCl2 < BCl3 < CCl4
  • d)
    LiCl > BeCl2 > BCl3 > CCl4
Correct answer is option 'C'. Can you explain this answer?

As we move in period from Li → Be → B → C, the electronegativity (EN)  increases and hence the EN difference between the element and Cl decreases and accordingly the covalent character increases Thus option (c) i.e., LiCl < BeCl2 < BCl3< CCl4 is correct.

B) BeCl2 c) BCl3 d) CCl4

The covalent bond character is determined by the electronegativity difference between the atoms involved in the bond. LiCl has the highest electronegativity difference between Li and Cl, so it has the most ionic character. BeCl2 has a slightly lower electronegativity difference, so it has a slightly lower ionic character. BCl3 has an even lower electronegativity difference, so it has a lower ionic character. CCl4 has the lowest electronegativity difference, so it has the least ionic character and the highest covalent bond character.
