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.

A solution at $20^{\circ} C$ is composed of 1.5 mol of benzene and 3.5 mol of toluene. If the vapour pressure of pure benzene and pure toluene at this temperature are 74.7 torr and 22.3 torr, respectively, then the total vapour pressure of the solution and the benzene mole fraction in equilibrium with it will be, respectively:
