Question

I don't understand determining the shape- tetrahedal, trigonal, linear of molecular shapes when the molecule is large like Urea. Can anyone help? It appears there are multiple shapes...

Answer 1

there is a tetrahedron example of methane other molecules that are tetrahedrons are ammonia and water

Answer 2

trigonal and linear are molecules existing in a single plane

Answer 3

So when I describe the shape of urea, NH2CONH2, would I have a tetrahedral around nitrogens & trigonal pymarid around carbond?

Answer 4

good discussion here:
