On heating with concentrated NaOH solution in an inert atmosphere of CO 2 , white phosphorus gives a gas. Which of the following statement is incorrect about the gas?

Question

Philoid · Accepted Answer

As trihalides of nitrogen family act as lewis base due to presence of one lone pair of electron and have ability to donate it. In comparison to NH₃ and PH₃ size of central atom is larger in PH₃ and electron density on phosphorous decrease and less available for protonation. Therefore PH₃ is less basic than NH₃. Hence (iv) is correct statement

When white phosphorous react with NaOH and water it produce phosphine gas which is very harmful, and its solution in water also decomposes in the presence of sunlight. Hence (i) and (ii) statement sare also correct.

The incorrect statement is (iv).

Hence the correct option is (iv).
