Answer:
6 hydrogen, three carbon (CH2=CH-CH3)
Step-by-step explanation:
Carbon atoms can bond to four other atoms
CH2=CH-CH3
First carbon is bonded to C(double) and 2H = 4 bonds
Second carbon is bonded to C(double), C (single) and one H = 4 bonds
Third carbon is bonded to one carbon(single) and three H= 4 bonds
