MCQ
Which can be described as a molecule with residual bonding capacity
  • $BeC{l_2}$
  • B
    $NaCl$
  • C
    $C{H_4}$
  • D
    ${N_2}$

Answer

Correct option: A.
$BeC{l_2}$
a
At room temperature, it exists as a dimer $\left( Be _2 Cl _4\right)$, so it has residual bonding capacity because although $BeCl _2$ is a complete, neutral molecule, it can form bonds with another molecule to attain further stability.
