Answer: The number of hydrogen atoms must be 6.
Explanation:
Alkenes are unsaturated hydrocarbons in which a single bond is present between carbon and hydrogen atoms and double bond is present between carbon and carbon atoms.
The general formula for writing an alkene is given as [tex]C_nH_{2n}[/tex] where, n = 1, 2, 3, 4....
It is given that number of carbon atoms are 3, which means that n = 3.
Putting (n = 3) in above expression, we get:
[tex]n=3:C_3H_{2(3)}=C_3H_6[/tex]
Hence, the number of hydrogen atoms must be 6.
