NTA JEE Main 11th April 2023 Shift 2

Given below are two statements:
Statement I: In the metallurgy process, sulphide ore is converted to oxide before reduction.
Statement II: Oxide ores in general are easier to reduce.
In the light of the above statements, choose the most appropriate answer from the options below:

Given below are two statements, one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: A solution of the product obtained by heating a mole of glycine with a mole of chlorine in presence of red phosphorous generates chiral carbon atom.
Reason R: A molecule with 2 chiral carbons is always optically active.

One mole of P$$_4$$ reacts with 8 moles of SOCl$$_2$$ to give 4 moles of A, x mole of SO$$_2$$ and 2 moles of B. A, B and x respectively are

If Ni$$^{2+}$$ is replaced by Pt$$^{2+}$$ in the complex [NiCl$$_2$$Br$$_2$$]$$^{2-}$$, which of the following properties are expected to get changed?
A. Geometry
B. Geometrical isomerism
C. Optical isomerism
D. Magnetic properties

Match List I with List II

Given below are two statements, one is labelled as assertion A and the other is labelled as Reason R.
Assertion A: [CoCl(NH$$_3$$)$$_5$$]$$^{2+}$$ absorbs at lower wavelength of light with respect to [Co(NH$$_3$$)$$_5$$(H$$_2$$O)]$$^{3+}$$
Reason R: It is because the wavelength of light absorbed depends on the oxidation state of the metal ion.

The magnetic moment is measured in Bohr Magneton (BM). Spin only magnetic moment of Fe in [Fe(H$$_2$$O)$$_6$$]$$^{3+}$$ and [Fe(CN)$$_6$$]$$^{3-}$$ complexes respectively is:

Product [X] formed in the above reaction is :

Compound 'B' is :

Given below are two statements:
Statement I: Ethane at 333 to 343 K and 6-7 atm pressure in the presence of AlEt$$_3$$ and TiCl$$_4$$ undergoes addition polymerization to give LDP.
Statement II: Caprolactam at 533-543 K in H$$_2$$O through step growth polymerizes to give Nylon 6.
In the light of the above statements, choose the correct answer from the options given below:
