O
CH₃CH₂C - Cl + 2NH₃ > ?

Please write carefully what CH₃CH₂C - Cl is

CH₃CH₂Cl? CH₃CH=CH-Cl ? Else?

expert,

You missed the question & the formula. The question is how to show/or illustrate a double bond in the posting. Sorry if this was not made clear.

My formula - O
CH₃CH₂C - Cl + 2NH₃ > ?

How do I show the double bond between the 1st C and the O?


What you wrote - CH₃CH₂Cl? CH₃CH=CH-Cl ?

The formulas are very different.

To draw the structures I recommend downloading software. There are free programs, and most higher level programs are available for free trial and discounts for students.

For simple situations like in your case there is no need putting oxygen atom above the carbon. You can write it like
CH₃-C(O)-CH₃ (acetone) or
CH₃-CH₂-CH=O or O=CH-C₂H₅ (both correct for propionaldehyde)

In your case, if you mean the double bond between O and C,

O
!!
CH₃CH₂C - Cl

then the structure doesn't make sense anyway. Carbon must have four bonds, not six like in your case. That’s why I asked you to provide the correct structure. Maybe you mean this?

...............O
...............!!
CH₃CH₂C - Cl

Better write it this way:

CH₃-CH₂-C(O)-Cl or simply CH₃CH₂C(O)Cl

In that case the reaction is

CH₃CH₂C(O)Cl + 2 NH₃ = CH₃CH₂C(O)NH₂ + NH₄Cl

I also recommend for more complex drawings to use these tools provided on this website:

For example, I drew your reaction here using Marvin Sketch tool
