Which orbitals of the following are overlapped and form sigma bond ? 1s - 1s, 2s - 2s, 1s - 2s, 2p_(x) - 2p_(x) , 2p_(y)- 2p_(y) , 2p_(z) - 2p_(z)

Which orbitals of the following are overlapped and form sigma bond ?

1.	Which orbitals of the following are overlapped and form sigma bond ? 1s - 1s, 2s - 2s, 1s - 2s, 2p_(x) - 2p_(x) , 2p_(y)- 2p_(y) , 2p_(z) - 2p_(z)
Answer» SOLUTION :`SIGMA` -bond is FORM by FOLLOWING overlapping 1s - 1s, 2s - 2s , 1s-2s, `2p_(z) - 2p_(z) ` `sigma`-bond is not formed by overlapping of `2p_(y)- 2p_(y) and 2p_(x) - 2p_(x)`.
