(C) 1. (A) Energy The correct molecular orbital diagram for F2 molecule in the ground state is Energy In 10 28 lo 20 2p 2p 1 20 10* 2s lo 20 2p (B) Aak (D) Energy Energy 1x 20 20 10* 2s la 2p 1x 2p 2. Consider the following statements related to colloids. (1) Lyophobic colloids are not formed by simple mixing of dispersed phase and dispersion medium. (II) For emulsions, both the dispersed phase and the dispersion medium are liquid. (III) Micelles are produced by dissolving a surfactant in any solvent at any temperature. (IV) Tyndall effect can be observed from a colloidal solution with dispersed phase having the same refractive index as that of the dispersion medium. The option with the correct set of statements is (A) (I) and (II) (C) (III) and (IV) (B) (II) and (III) (D) (II) and (IV) 3. In the following reactions, P, Q, R and S are the major products. (i) Mg, dry ether (ii) HO (i) Mg, dry ether (ii) CO, dry ether (iii) H3O+ (iv) NaOH (i) Mg, dry ether (ii) CH3CHO, then HO (iii) CrO3 (i) ethanolic NaCN (ii) H/ Ni CI (iii) CHCl3/OH, A (iv) LiAlH4, then HO R BBYJU'S Aakas The correct statement about P, Q, R and S is (A) P is a primary alcohol with four carbons. (B) Q undergoes Kolbe's electrolysis to give an eight-carbon product. (C) R has six carbons and it undergoes Cannizzaro reaction. (D) S is a primary amine with six carbons.
