Lewis Structure Help: CH3NCO Bonding Scheme

[Rasine]

i am attempting to figure out the lewis structure/ bonding scheme for CH3NCO.

so far i have: O=C=C-N-H
l l
H H
the Hs are attached to the second C then the N

the formal charges seem to be ok

i have a formal charge of 0 for O, C, N
i have a formal charge of 1 for all the H

what do you think?

Your methyl group (CH3) should be together.

Perhaps you are referring to methyl cyanate (CH₃OCN) ?
$${\text{H}}\mathop {\text{C}} \limits_{\text{H}}^{\text{H}} {- \text{O}} - {\text{C}} \equiv {\text{N}}$$

Otherwise, as written, "CH₃NCO" refers to
$${\text{H}}\mathop {\text{C}}\limits_{\text{H}}^{\text{H}} - {\text{N}} = {\text{C}} = {\text{O}}$$

(* perhaps we should implement a $$\LaTeX$$ for molecular structures?)
