12. The treatment of galena with HNO3 produces a gas that is (A) paramagnetic (C) an acidic oxide (B) bent in geometry (D) colorless 13. Considering the reaction sequence given below, the correct statement(s) is (are) 1. Br2, red phosphorous H3C COOH 2. HO 2. NaOH 3. HO* (A) P can be reduced to a primary alcohol using NaBH4. (B) Treating P with conc. NH4OH solution followed by acidification gives Q. Cation (C) Treating Q with a solution of NaNO2 in aq. HCI liberates N2. (D) P is more acidic than CH3CH2COOH. COOH COOH 14. Considering the following reaction sequence, NO2 P R HO S T H3C U the correct option(s) is (are) (A) P H2/Pd, ethanol R = NaNO2/HCI (B) P = Sn/HCI Ak R=HNO2 COOH BBYJU'S (C) S = H3C N20 T = (D) Q = HOOC H3C U = 1. H3PO2 2. KMnO4 KOH, heat S = H3C OH U 1. CH3CH2OH 2. KMnO4 - KOH, heat NO2 = R H2/Pd, ethanol T = H3C
