PROBLEM 1.22 Give the hybridization state of each carbon in the following

compounds:

(a) Carbon dioxide (0 = C = O)

(d) Propene (C*H_{3}*CH = C*H_{2})

(b) Formaldehyde (H_{2}*C = O)

(e) Acetone [(CH 3 ) 2 C = OI

(c) Ketene (H_{2}*C = C = O)

(f) Acrylonitrile ( C*H_{2} =CHC equiv N)

SAMPLE SOLUTION

(a) Carbon in C*O_{2} is directly bonded to two other atoms. It

is sp-hybridized.
