Subject: Inorganic Chemistry · Chapter: Organometallic Compounds · Topic: Organometallics – General · Exam: JAM 2005-2022 · Marks: 2 · Difficulty: Hard

The correct order of $\mathrm{M}-\mathrm{C}(\mathrm{M}=\mathrm{Ti}, \mathrm{V}, \mathrm{Cr}$ and Mn$)$ bond stretching frequency is: (Given: Atomic number of $\mathrm{Ti}=22, \mathrm{V}=23, \mathrm{Cr}=24$ and $\mathrm{Mn}=25$ )

(a)$\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}<\mathrm{Cr}(\mathrm{CO})_{6}<\left[\mathrm{Mn}(\mathrm{CO})_{6}\right]^{+}<\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}$

(b)$\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}<\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}<\mathrm{Cr}(\mathrm{CO})_{6}<\left[\mathrm{Mn}(\mathrm{CO})_{6}\right]^{+}$

(d)$\left[\mathrm{Mn}(\mathrm{CO})_{6}\right]^{+}<\left[\mathrm{V}(\mathrm{CO})_{6}\right]^{-}<\mathrm{Cr}(\mathrm{CO})_{6}<\left[\mathrm{Ti}(\mathrm{CO})_{6}\right]^{2-}$
