Which among the following is electron deficient compound?
1 \(\mathrm{CCl}_{4}\)
2 \(\mathrm{SiF}_{4}\)
3 \(\mathrm{PCl}_{5}\)
4 \(\mathrm{BCl}_{3}\)
Explanation:
In \(\mathrm{BCl}_{3}\), \(\mathrm{B}\) has only six electrons surrounding it, thus it is electron deficient molecule. ( \(3 \sigma\) bonds, so six electrons)
