If [Cr(H2O).]3+ is violet and [Cr(NH3)6]3+ is yellow, which one of these statements is false ?...

If [Cr(H2O).]3+ is violet and [Cr(NH3)6]3+ is yellow, which one of these statements is false ? 750 400 Red Violet 630 430 Orange Blue 590 480 Yellow Green 560 O [Cr(H20)6]3+ has three unpaired electrons. O NH3 is a stronger field ligand than H20. O [Cr(H20)6]3+ absorbs yellow light while [Cr(NH3)6]3+ absorbs violet light. The crystal field splitting energy (A) is greater for [Cr(H20).]3+ than for [Cr(NH3)613+. O [Cr(NH3)613+ is paramagnetic.
