A. Bent
B. Linear
C. Tetrahedral
D. Trigonal Plannar

Answer 1

I would have to say B. Linear

I hope this helps!

Answer 2

Answer : The correct option is, (B) Linear

Explanation :

Formula used :

`\text{Number of electrons}=(1)/(2)[V+N-C+A]`

where,

V = number of valence electrons present in central atom

N = number of monovalent atoms bonded to central atom

C = charge of cation

A = charge of anion

Now we have to determine the hybridization of the
`BeH_2` molecules.

`\text{Number of electrons}=(1)/(2)* [2+2]=2`

The number of electrons is 2 that means the hybridization will be
`sp` and the electronic geometry of the molecule will be linear.

The three-dimensional shape of the molecule with the Lewis structure are shown below.
