Question

Heating white phosphorus with conc. NaOH solution gives mainly

Options
  1. a

    Na3P\mathrm{Na_3P} and H2O\mathrm{H_2O}

  2. b

    H3PO\mathrm{H_3PO} and NaH

  3. c

    P(OH)3\mathrm{P(OH)_3} and NaH2PO4\mathrm{NaH_2PO_4}

  4. d

    PH3\mathrm{PH_3} and NaH2PO2\mathrm{NaH_2PO_2}

Correct Answerd

PH3\mathrm{PH_3} and NaH2PO2\mathrm{NaH_2PO_2}

Detailed Solution

Strategy: Use hybridization and VSEPR theory to identify molecular shapes.

Step 1: Comparison Identify which pairs of compounds (e.g., \ceXeF4\ce{XeF4} and \ceXeO2F2\ce{XeO2F2}) have the same or different hybridization and shapes.

Step 2: Selection The characteristic identified (e.g., isostructural nature or same hybridization) corresponds to the correct answer.

Answer: (Option) [d] [Based on shape/hybridization in question]\boxed{\text{Answer: (Option) [d] [Based on shape/hybridization in question]}}
