Question

Shape of the molecule having sp hybridization is:

• A. Linear
• B. Trigonal planar
• C. Square planar
• D. Tetrahedral

Answer 1

The correct option is A

Linear

1s + 1p $\to$ $2sp$ hybrid orbitals
1s + 2p $\to$ ${3sp}^2$ hybrid orbitals
1s + 3p $\to$ ${4sp}^3$ hybrid orbitals
1s + 3p + 1d $\to$ $5{sp}^{3}d$ hybrid orbitals
Now, lets have a look at how many hybrid oribtals we have.
Two $sp$ hybrid orbitals
We have to arrange 2 $sp$ hybrid orbitals around the central atom so that it will have least repulsion.

$\to$ both the orbital should be ${180}^{\circ }$ apart from each other for having least repulsion

So, it is linear structure
