Question

which of the following compund is election deficient A NF3 B SiCL4 C PCL5 D BeCL2​

Answer 1

Answer:

Out of the following compounds (A) NF3 is electron deficient.

Explanation:

N has 6 electrons even after sharing with F (2 less than the octet).

Answer 2

BeCl2 is an electron deficient compound.

• The central atoms of different chemical compounds are unable to complete their octet structure due to the lack of electrons. These chemical compounds are known as the electron deficient compound.
• Similarly, beryllium is the central atom of the BeCl2.
• Now, the central atom Be only have 2 valence electrons which cannot complete it's octet. But it helps to fill the octet of the chlorine atoms.
• Due to the non fulfilment of the octet of the central atom, we can consider this chemical compound as an electron deficient compound.
