QJEEM11Ch4031: JEE Main 2011 Chemistry - Class 12 JEEM11Ch4031 Solution: Which of the following statement is wrong?
Which of the following statement is wrong?
Multiple Choice Options
- A Nitrogen cannot form bond.
- B Single N – N bond is weaker than the single P – P bond
- C N2O4 has two resonance structures
- D The stability of hydrides increases from NH3 to BiH3 in group 15 of the periodic table
Step-by-Step Verified Solution
The case of formation and stability of hydrides decreases rapidly from to . This is evident from their dissociation temperature which decreases from to As we go down the group the size of central atom increases and thus metal-hydrogen bond becomes weaker due to decreased overlap between the large central atom and small hydrogen atom.
