What are the respective hybridizations of the imine nitrogen and carbonyl carbon of the CPV B-state as it is depicted in the pas
horsena [70]

Answer:

C) sp2 and sp2

Explanation:

The hybridization depens on the ammount and type of bonds the atom analized has in the molecule.

For example:

  • A C atom bonded to 4 H atoms has a sp3 hybridization.
  • A C atom bonded to 2 H atoms and to 1 C with a double bond (like in ethene) has a sp2 hybridization
  • A C bonded to 1 H and 1 C with a triple bond (like in ethyne) has a sp hybridization.

Analyzing the type and amount of unions of the nitrogen and the carbonyl you will be able to determine the hybridization.

In the imine, the N atom has a double bond to a C and a simple bond two other C, plus the lone pair of electrons (counts as a bond) so it will have a sp2 hybridization.

In the carbonyl, the C has two simple bonds to other C and a double bond to an oxygen atom. It will also have a sp2 hybridization
