Question

$InB{F}_3,BC{l}_3$ and $BB{r}_3$ the stability order is

• A. ${\text{BF}}_3>{\text{BCl}}_3>{\text{BBr}}_3$
• B. $BC{l}_3>B{F}_3>BB{r}_3$
• C. $BB{r}_3>BC{l}_3>B{F}_3$
• D. $BB{r}_3>B{F}_3>BC{l}_3$

Answer 1

Answer: (A)

${\text{BBr}}_3\text{ < }{\text{BCl}}_3\text{ < }{\text{BF}}_3$ order of back bonding.

As the ordr of back bonding increases the stability increases
