1a. How many carbons atoms are present in but-2-ene? 1b. How many carbons atoms are present in 2-methyl butane? Thank you.
An incomplete Lewis structure is shown below. The structure only
shows the atoms and how they are connected. The molecule has a net
charge of +1.
Complete the Lewis structure giving all atoms full octets. If
there is more than one way to do this, draw resonance structures
showing all possibilities. If not, just draw one Lewis structure.
Be sure to write in any non-zero formal charges. SHOW ALL
