Naming molecular compounds from skeletal ?

http://gyazo.com/057edf5d8f0af63c772e7572cf02f5cf

How do you write the molecular formula of a skeletal like that ?

And also does anyone have a way of getting 5/5 or 4/4 on questions which ask for bond angles then explaining them ? Like a guide or modal answer ?

And how do you calculate bond angles ?

Well I'd draw out the displayed and count them really. For a model answer look at 2 or 3 mark schemes which have a question on them.

How would you draw it out ?

Every node represents a carbon atom. You just need to draw in enough hydrogens to get the carbon valence up to 4.

For the bond angle questions just make sure you talk about bonded and lone pairs - and then say that lone pairs repel more than bonded. This is pretty much all there is to it. (At A level anyway.)
