15. We have taken a saturated solution of AgBr. Ksp of AgBr is 12 1014. If 107 mole of AgNO3 are added to 1 litre of this solution find conductivity (specific conductance) of this solution in terms of 107 Sm units. Given: 610 Sm mol (AB) =810 Sm mol (Br) 2 (NO3) =7x10 Sm mol (a) 55 (b) 75 (c) 65 16. Incorrect order of Rate of Reduction among the following is: 17. (A) R-C-OH R-C-CI - Reduction with Borane (d) 45 0 O (B) R-C-H R-C-OH - Reduction with LiAlH (C) R-C=C-R>R-CH=CH-R - Reduction with H/Ni 0 0 (D) R-C-CI >>R-C-OH Reduction with DIBAL-H Which of the following cation produces ppt. with only one of the given condition (I) In aqueous solution produce ppt with dil. HCI (II) In acidic aqueous solution produce ppt with HS (a) Pb+2 (b) Hg2+ (c) Ag (d) Sn+2
