JEE Main Chemistry question
The following are some statements related to group 15 (VA) hydrides: I. Reducing property increases from to II. Tendency to donate the lone pair decreases from to III. Thermal stability of hydrides decreases from to IV. Bond angle of hydrides decreases from to
The correct statements are [EAMCET 2007]
Answer: (A)
Solution
All four trends are chemically correct down group 15: reducing power of the hydrides increases (weaker bonds donate H more readily); basicity/lone-pair-donating ability decreases (lone pair becomes more diffuse, less
