Answer #1

The structure of N2H2 is:

here N is SP2 hybridised (because it form 2 sigma bond and has a lone pair. pi bonds are not considered for hybridisation)

So,
SP2 orbital of N will overlap to form sigma bond

so, sigma bond is formed by SP2 orbital of N and s orbital of H

Since pi bonds are not part of hybridisation,
it is formed by 2p orbital of N and 2p orbital of N

only correct statement is:
C) sp2 orbitals on each nitrogen overlap and form a sigma bond

Answer:
C) sp2 orbitals on each nitrogen overlap and form a sigma bond

Natural Bond Orbitals Natural Bond Orbitals (NBOs) convert molecular orbitals to the form of localised bonding orbitals that correspond to Lewis structures. Natural bond orbitals attempt to provide the most accurate natural Lewis structure. The NBOs are localised and are thus different to MOs - it is important not to over-interpret NBOs - NBOs give an indication of bonding and electronic structure in the framework of Lewis structures. In this exercise you will explore the bonding description of methanol from...

are the following statements true or false? One sigma bond and one pi bond comprise a double bond. A triple bond consists of one sigma bond and two pi bonds. End-to-end overlap results in a sigma bond. A double bond consists of two pairs of electrons. Bonds formed from atomic p orbitals are always sigma bonds. A pi bond restricts rotation about the sigma bond axis.
