ABC26IN0243 · Organometallic Compounds
Subject: Inorganic Chemistry · Chapter: Organometallic Compounds · Topic: Organometallic Compounds – General · Exam: CSIR-NET 2013 · Marks: 2 · Difficulty: Easy
Among the following, the correct statement is
(a)$\mathrm{CH}$ is isolobal to $\mathrm{Co(CO_3)}$
(b)$\mathrm{CH_2}$ is isolobal to $\mathrm{Ni(CO)_2}$
(c)$\mathrm{CH}$ is isolobal to $\mathrm{Fe(CO_4)}$
(d)$\mathrm{CH_2}$ is isolobal to $\mathrm{Mn(CO)_4}$
Answer
Explanation
$\mathrm{CH}\rightarrow 4+1=5e$ $\mathrm{Co(CO)_3}\rightarrow 9+6=15e$ $\mathrm{CH}$ $\mathrm{Co(CO)_3}$ But, $\mathrm{CH_2}\rightarrow 4+2=6e$ $\mathrm{Ni(CO)_2}\rightarrow 10+4=14e$ — not isolobal
