Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 1

Inner Transition Metals & Bio-inorganic - Question 2

Which of the following metal is used for magnetic resonance imaging (MRI)

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 2

Species having large number of unpaired electron can be used in MRI. As Gd has seven unpaired electron. Hence, used in MRI.

Inner Transition Metals & Bio-inorganic - Question 3

The function and metal associated with carboxy peptidase are respectively:

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 3

Carboxypeptidase is responsible for cleavage of peptide bond as it has Zn2+ ion at active centre

Inner Transition Metals & Bio-inorganic - Question 4

Which of the following compounds does not involve in the electron transfer in photosynthesis:

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 4

Cytochrome b is not involve in electron transfer in photosynthesis

Inner Transition Metals & Bio-inorganic - Question 5

The compound which do not involve in the electron transfer in any process of living beings:

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 5

Tarnsferrin is involved in transport of iron and have Fe in +3 oxidation state

Inner Transition Metals & Bio-inorganic - Question 6

Which of the following is not a heme protein?

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 6

Haemocyanin, do not contain Fe and porphyrin. Hence, it is a non-heme protein.

Inner Transition Metals & Bio-inorganic - Question 7

The substances which act as iron transport and iron storage respectively are:

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 7

Transferrin and ferrtin are responsible for Fe transport and storage respectively.

Inner Transition Metals & Bio-inorganic - Question 8

The transition elements of 4d and 5d series which have no similar size are

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 8

*Answer can only contain numeric values
Inner Transition Metals & Bio-inorganic - Question 9

The value of spin multiplicity in ground state term of Nd3+  is _____


Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 9



*Answer can only contain numeric values
Inner Transition Metals & Bio-inorganic - Question 10

The value of J in ground state term of Pr3+ is ..........


Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 10


Inner Transition Metals & Bio-inorganic - Question 11

Which of the following aquated Ln3+ ion is not coloured

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 11

 there is 4f-5d transition. It absorbs in UV. Therefore, it is colourless

Inner Transition Metals & Bio-inorganic - Question 12

The correct statement about Ln3+ ions is
(1) Their magnetic moments increase with increase in number of unpaired electrons
(2) All Ln3+ ions are coloured
(3) The crystal field splitting energy  increases with increase in ligand field strength
(4) Most of the Ln3+ ions show sharp bands in their absorption spectra

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 12

(1) The magnetic moment of Ln3+ ions depends on the spin-orbit coupling, not on the number of unpaired electrons.
(2) La3, Ce3+, Gd3+, Yb3+ and Lu3+ colourless
(3) Since, the 4f-orbitals buried deep inside the atom, there is no or little interaction between Ln3+ ions and the ligands. Therefore, zero value does not depend on the nature of ligand.
(4) For the same reason discussed in point 3, most of the Ln3+ ions show sharp peaks.

Inner Transition Metals & Bio-inorganic - Question 13

The lanthanides which show abnormal behaviour towards lanthanide contraction are

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 13

In Eu and Yb metals, which have the stable electronic configuration 4f7 6s2 and 4f14 6s2. Only two electrons contribute in the M-M bonding resulting in the +2 oxidation state. In the other lanthanoids, three or more electrons participate in M-M bonding resulting in the +3 oxidation state of metal.

Inner Transition Metals & Bio-inorganic - Question 14

The substances containing iron and responsible for oxygen transport are

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 14

Hemoglobin and hemerythrin contain iron and both are responsible for oxygen transport.

Inner Transition Metals & Bio-inorganic - Question 15

The correct statement about cytochrome c-oxidase is

Detailed Solution for Inner Transition Metals & Bio-inorganic - Question 15

Cytochrome c contains a heme iron metal center that is essential to its function. During the electron transport process, this heme iron interconverts between the Fe3+ and Fe2+ oxidation states, which allows for electrons to be accepted and donated.
