Which of the following order is correct?

Question

Which of the following order is correct? (A) AlCl3 < MgCl2 < NaCl: Polarising powre (B) CO > CO2 > HCO2- CO32-: Bond length (C) BeCl2 < NF3 < NH3: Dipole moment (D) H2S > NH3 > SiH4 BF3: Bond angle

Tardigrade Admin · Accepted Answer

(a) Polarising power of cations increases with the increasing charge.

(b) Bondorder propto (1/ text Bondlength ) Bondorder =( text Bondorderofeach C- text Obond / text Totalno.ofresonatingstructures ) Hence, the decreasing order of bond length is Correct order of dipole moment: BeCl 2< NF 3< NH 3 (d) Correct order of bond angle:

Q. Which of the following order is correct?

$A lC l_{3} < M g C l_{2} < N a Cl$ : Polarising powre

$CO > C O_{2} > H C O_{2}^{-} C O_{3}^{2 -}$ : Bond length

$B e C l_{2} < N F_{3} < N H_{3}$ : Dipole moment

$H_{2} S > N H_{3} > S i H_{4} B F_{3}$ : Bond angle
