I was a little confused with that one, even with doing the dot structure.
1. 4valence of carbon + 3valence for the hydrogens - 1valence since it is a + = 6 total valence available
2. need 6valence for the hydogens and 8valence for the carbon= 14 total needed
3. 14-6=8 need bonds
4. 8/2 = 4 bonds
but how can I form 4 bonds when each H will only have a single bond?
