Identify the hybridization of each carbon atom for the molecule above

Carbons starting from the left end:

Refer to the sketch attached.

The hybridization of a carbon atom depends on the number of electron domains that it has.

Each chemical bond counts as one single electron domain. This is the case for all chemical bonds: single, double, or triple. Each lone pair also counts as one electron domain. However, lone pairs are seldom seen on carbon atoms.

Each carbon atom has four valence electrons. It can form up to four chemical bonds. As a result, a carbon atom can have up to four electron domains. It has a minimum of two electron domains, with either two double bonds or one single bond and one triple bond.

Starting from the left end (H₂C=CH-) of the molecule:

a compound is a molecule made of atoms from different elements.

a. by the combination of an unlimited number of elements

i have no clue hope you find the answer
