how to determine sigma bonds

count the number of single bonds (count 1 for every double and triple bond)

how to determine pi bonds

count the number of additional bonds (1 in a double, 2 in a triple)

how to determine sp

look for atoms with 2 things around it

how to determine sp²

look for atoms with 3 things around it, or if no sp then double # of pi bonds

how to determine sp³

look for atoms with 4 things around it
