what is the sp hybrid orbitals for carbon molecules in CH3-C=C-CH2OH?

Answer 1

Count the bonding. Single bonds count as single, double as single, triple as single.
Four bonds (C in CH3 and -CH2-) = sp3
Three bonds (C in C=C and C=0) = sp2
You have no triple bonds but if one were there, that would be two bonds (-CtripleC-) and that is sp.
I don't think it is necessary to count bonds, all single bonds = sp3
double bond = sp2
triple bond = sp
