Which of the following statement(s) is/are correct?a)CO + Cl2 in prese...
Statement a) CO + Cl2 in presence of light yield phosgene gas:
This statement is correct. When carbon monoxide (CO) reacts with chlorine gas (Cl2) in the presence of light, it forms phosgene gas (COCl2). This reaction is an example of a photochemical reaction, where the energy from light is used to break the bond between chlorine molecules and allow them to react with carbon monoxide.
Statement b) Solid PCl5 exists as PCl4- and PCl6-:
This statement is correct. Solid phosphorus pentachloride (PCl5) exists as a complex equilibrium mixture of PCl4+ and PCl6- ions. PCl5 is a covalent compound, but in the solid state, it undergoes ionic dissociation to some extent. The PCl4+ ion is a trigonal bipyramidal species, while the PCl6- ion is octahedral in shape.
Statement c) NH3 is more volatile than PH3:
This statement is incorrect. Ammonia (NH3) is less volatile than phosphine (PH3). Volatility refers to the tendency of a substance to vaporize or evaporate. In this case, phosphine (PH3) has a higher vapor pressure and is more likely to evaporate compared to ammonia (NH3). This is because phosphine has weaker intermolecular forces (due to the presence of larger and more diffuse phosphorus atom) compared to ammonia, which leads to higher volatility.
Statement d) N3- is isoelectronic with N2O:
This statement is correct. Isoelectronic species are those that have the same number of electrons. Nitride ion (N3-) has a total of 10 electrons (7 from nitrogen and 1 from each of the three extra electrons), while nitrous oxide (N2O) also has a total of 10 electrons (5 from each nitrogen and 2 from oxygen). Therefore, N3- and N2O are isoelectronic.
In summary, the correct statements are a), b), and d). CO reacts with Cl2 in the presence of light to yield phosgene gas, solid PCl5 exists as PCl4+ and PCl6- ions, and N3- is isoelectronic with N2O.
