Give the hybridization of each carbon in the molecule below.

The hybridisation of C1 and C2 are sp3 and sp2 respectively.

Explanation:

Here the first carbon (C-1) formed four straight single bonds.

Linking to the electron theory (a fig.1 shown below) one electron from 2s orbital moves to the empty 2pz orbital.

The 2s and the three 2p orbitals hybridise and each orbital will be completed by one electron shared mutually with and from N, H, H, and the other C.

C-2 the second carbon has an sp2 because it forms a double bond with oxygen.

In the sp2 hybridisation the 2s orbital hybridises with only two 2p orbitals leaving the other 2p orbital unhybridised. The orbitals in sp2 is to be completed with one more electron each by sharing covalently with the C, O and the other O.

Note: The unhybridised p orbital is completed with the other shared electron of the oxygen. This forms the π bond in the carbon-oxygen double bond. (Fig 2. Shows  the electronic arrangements.)
