NEET Chemistry (general) MCQ Question
Type: MCQ-conceptual-Medium-Class 12
Which of the following statements about p-block elements is correct?
A
Nitrogen does not form pentahalides due to the absence of d orbitals.
B
PH3 has a higher boiling point than NH3 due to stronger hydrogen bonding.
C
The common oxidation state of halogens is +1.
D
Fluorine is predominantly found in nature as soluble fluorides.
Correct Answer
Option A
Detailed Explanation
Nitrogen's inability to form pentahalides is attributed to its lack of d orbitals, limiting its covalence to four. PH3 has a lower boiling point than NH3 due to the absence of hydrogen bonding, and the common oxidation state of halogens is -1, not +1. Fluorine is found mainly as insoluble fluorides.
