Subject: Inorganic Chemistry · Chapter: Organometallic Compounds · Topic: Organometallic Compounds – General · Exam: CSIR-NET 2019 · Marks: 2 · Difficulty: Medium
The expected number of co bands in the IR spectra of fac-$\mathrm{[Mo(PPh_3)_2(CO)_3]}$ and trans-$\mathrm{[Mo(PPh_3)_2(CO)_4]}$ are, respectively
(a)one and one
(b)Two and two
(c)two and one
(d)three and one
Answer
SELF-PRACTICE — the source book printed no answer.
Nothing is invented here, so this question has no answer on record.
Explanation
The number of CO bands in fac-$[\mathrm{Mo(PPh_3)_2(CO)_3}]$ = 2 The number of CO bands in trans-$[\mathrm{Mo(PPh_3)_2(CO)_4}]$ = 1
