Test: Organometallic Chemistry- 2 - Question 1

Which one of the following has an optical isomer:

Test: Organometallic Chemistry- 2 - Question 2

The existence of two different coloured complexes with the composition of [Co(NH3)4Cl2]+ is due to:

Test: Organometallic Chemistry- 2 - Question 3

Which one of the following complexes is not expected to exhibit isomerism:

Detailed Solution for Test: Organometallic Chemistry- 2 - Question 3

Test: Organometallic Chemistry- 2 - Question 4

The number of metal-metal bonds in [W2(OPh)6] is:

Detailed Solution for Test: Organometallic Chemistry- 2 - Question 4

No of metal - metal bond= (18n - TVE)/2
Here, TVE = 2(6) + 6(3)

= 30
n = 2 (n denotes the number of metals present)

Hence, No of metal - metal bonds= (36-30)/2

= 3 metal - metal bonds.

Test: Organometallic Chemistry- 2 - Question 5

Among the following, the correct statement is:

Test: Organometallic Chemistry- 2 - Question 6

Which of the following metal fragments, d9–MLn is isolabal with CH?

Test: Organometallic Chemistry- 2 - Question 14

The correct order of νNO (cm–1) in the following compounds is:

Test: Organometallic Chemistry- 2 - Question 15

If the bond length of CO bond in carbon monoxide is 1.128 Å. Then what is the value of CO bond length in Fe(CO)5:

Detailed Solution for Test: Organometallic Chemistry- 2 - Question 15
  • In Fe(CO)5​ there exists a synergic bond between Fe and CO. Due to synergic bond formation between metal and CO, the bond order of CO decreases.
  • As bond order decreases the Bond length increases.Here the only option having greater bond length than 1.128A0 is option A- 1.158A0.
Test: Organometallic Chemistry- 2 - Question 16

Which of the following in not suitable as catalyst for hydroformylation:

The catalyst used for the oxidation of ethylene to acetaldehyde is:

Test: Organometallic Chemistry- 2 - Question 18

Regarding the catalytic cycle of hydrogenation of alkanes involving RhCl(PPh3)3 as t he catalyst, the correct statement is:

Test: Organometallic Chemistry- 2 - Question 19

The catalyst used in the conversion of ethylene to acetaldehyde using Wacker process:

Test: Organometallic Chemistry- 2 - Question 20

Test: Organometallic Chemistry- 2 - Question 21

Metals used in automobile catalytic converters are:

Test: Organometallic Chemistry- 2 - Question 22

Active catalytic species for hydroformylation is:

Test: Organometallic Chemistry- 2 - Question 23

Wikinson’s catalyst:

Test: Organometallic Chemistry- 2 - Question 24

An intermediate formed during the hydroformylation of olefins using Co2(CO)8 as catalyst is:

Test: Organometallic Chemistry- 2 - Question 25

In Monsanto acetic acid process shown below, the role of HI is:

Detailed Solution for Test: Organometallic Chemistry- 2 - Question 25

Correct Answer :- B

Explanation : The Monsanto acetic acid process is the major commercial production method for acetic acid. Methanol, which can be generated from synthesis gas ("syn gas", a CO/H2 mixture), is reacted with carbon monoxide in the presence of a catalyst to afford acetic acid. In essence, the reaction can be thought of as the insertion of carbon monoxide into the C-O bond of methanol, i.e. the carbonylation of methanol.

Test: Organometallic Chemistry- 2 - Question 26

The reaction of acetyl chloride and AlCl3 with ferrocene gives:

Test: Organometallic Chemistry- 2 - Question 27

The infra–red starching frequency vCO of P-S follows the order:




Test: Organometallic Chemistry- 2 - Question 28

Ferrocene undergoes Vilsmeir reaction to yield:

Test: Organometallic Chemistry- 2 - Question 29

In hydroformylation process, propene is converted into

Detailed Solution for Test: Organometallic Chemistry- 2 - Question 29

Hydroformylation, also known as oxo synthesis or oxo process, is an industrial process for the production of aldehydes from alkenes. It is important because aldehydes are easily converted into many secondary products. For example, the resulting aldehydes are hydrogenated to alcohols that are converted to detergents.

When propene reacts with CO and H2 then butanal is formed.

H2 + CO + CH3CH=CH2 → CH3CH2CH2CHO ("normal")

H2 + CO + CH3CH=CH2 → (CH3)2CHCHO ("iso")

Hence B is correct
