NTA Abhyas NEET2020Chemistryp Block Elements (Group 13 & 14)Practice
In B F 3 , B C l 3 and B B r 3 the stability order is
Options
- ABF 3 > BCl 3 > BBr 3
- BB C l 3 > B F 3 > B B r 3
- CB B r 3 > B C l 3 > B F 3
- DB B r 3 > B F 3 > B C l 3
Correct answer
A. BF 3 > BCl 3 > BBr 3
Step-by-step solution
BBr 3 <   BCl 3 <   BF 3 order of back bonding. As the ordr of back bonding increases the stability increases
