The correct order boiling point as well as melting point of 15th group

1.	The correct order boiling point as well as melting point of 15th group element hydride
Answer» The correct order of boiling point as well as melting point of 15th group element hydride WOULD be Bi>N>Sb>As>P (according to melting point) The melting point increases upto arsenic and then DECREASES upto bismuth. Thus melting point of group 15 increases down the group but its melting point decreasing at Sb and Bi due to the INERT pair of effect . & the correct order of boiling point would be N>P The boiling point of grou 15 hydrides decreases from ammonia to phosphine and then increases from phosphine to bismuth

The correct order boiling point as well as melting point of 15th group element hydride

Answer»

The correct order of boiling point as well as melting point of 15th group element hydride WOULD be

Bi>N>Sb>As>P (according to melting point)

The melting point increases upto arsenic and then DECREASES upto bismuth.

Thus melting point of group 15 increases down the group but its melting point decreasing at Sb and Bi due to the INERT pair of effect .

& the correct order of boiling point would be N>P

The boiling point of grou 15 hydrides decreases from ammonia to phosphine and then increases from phosphine to bismuth
