PH3 produces smoky rings when it comes in contact
with air because
Option A : PH3 reacts with water vapours
Option B : PH3 reacts with N2
Option C : PH3 burns in air
Option D : PH3 contains impurities of P2H4
Show/Hide Answer Key
Option D: PH3 contains impurities of P2H4
PH3 produces smoky rings when it comes with contact with air because PH3 contains impurities of P2 H4 which undergoes spontaneous combustion
CUET Chemistry Mock Test Question No: 10
The compound that cannot act both as oxidizing and reducing agent is
Option A : H2SO3
Option B : H3PO4
Option C : HNO2
Option D : H2O2
Show/Hide Answer Key
Option B: H3PO4
CUET Chemistry Question No: 11
Sulphur exhibits valencies of 2, 4 and 6, whereas oxygen has a valency of 2 due to
Option A : being less electronegative than S
Option B : presence of d-orbitals in S
Option C : S is bigger atom
Option D : S has higher ionisation potential
Show/Hide Answer Key
Option B: presence of d-orbitals in S
Due to presence of d-orbitals, sulphur can expand its valencies from 2 to 6, while oxygen has only one valency (2) due to the absence of d-orbital.

Water is much less volatile than H2S because
Option A : H2O has a bond angle of nearly 150°
Option B : hydrogen is loosely bonded with the sulphur
Option C : S-atom is less electronegative than O-atom
Option D : S-atom is more electronegative than O-atom
Show/Hide Answer Key
Option C: S-atom is less electronegative than O-atom
Water (H2O) is much less volatile then H2S because sulphur atom is less electronegative then O-atom and, hence does not form H-bonding like water
