Question

1) the shape p-orbital is a) sperical b) dum bell c) double dum bell d) complex 2) the axis which passes and connects the nuclei of the combing orbitals is called a) x-axis b) y-axis c) inter nuclear axis d) none 3) a covalent bond is formed by end-to-end overlamping of two atomic orbitals is known as ? 4) s-s overlapping is observed in a) H2 b) Cl2 c) He d) O2 ​

Answer 1

Answer:

1 = b) dum bell  

2 = c) inter nucleus axis  

3 = sigma bond

4 = H2  

Explanation:

1 = b) dum bell                             (reason=  it is a fact)

2 = c) inter nucleus axis              (scientist had given this name)

3 = sigma bond              ( end to end overlapping corresponds to sigma bond )

4 = H2                             (it only contains is orbitals so bonding occurs btw          them only )
