The hybridisation of each carbon in the following compound respectively is CH3-CO-CH2CN
sp3,sp2,sp3,sp
sp3,sp3,sp2,sp
sp3,sp2,sp, sp3
sp2,sp, sp3, sp3

sp3,sp2,sp3,sp
In the compound,
The C-atoms that is bonded to four different atoms involve four orbitals (1 of s and 3 of p- orbitals) during hybridisation. Hence, they have sp3 -hybridisation as in cases of (i) and (iii).
The C- atom bonded to three different atoms involves three orbitals (1 of s and 2 ofp-orbitals) Hence, the sp2-hybridisation in case of (ii).
The C-atom bonded to two different atoms involves two orbitals (1 of s and 1 of p-orbitals). Hence, the sp- hybridisation in case of (iv).
