A molecule or atom that is not bonded to C or H.

This is a structural formula, making the electron dot structure easy to draw. We begin from the left, with two H atoms attached to a C atom. This C atom is double bonded to another C atom. That second C atom has one H attached, and another single bond to another C atom. Finally, the last C atom is triple bonded to the Nitrogen.
Butane itself is C4H10, however when a bromine atom is attached to the second carbon, it becomes C4H9Br as one hydrogen is replaced by the bromine.
H H H ::: C : O : H , with 4 more dot at the C and the O atom each.
The Lewis dot diagram of CH2CHCN should be simple to draw from this structural formula. It starts with a C atom bonded to two H atoms and double bonded to another C atom. This C atom is single bonded to one H atom and single bonded to another C atom. The final C atom is triple bonded to a nitrogen atom.
In methane a C atom is surrounded by 4 H atoms.Now about the angle. There are 6 tetrahedral angles i.e H-C-H angles..Imagine a C atom in the center.A H atom on top of it and 3 H atoms below forming a triangle(to make it look simple).Now start from the H atom on top,go through the C atom to an H atom below.This way you get 3 tetrahedral angles right??Now start from an H atom below the C atom and go to another H which is below the C atom via C atom(keep this H atom in mind).This way you get 2.Now for the last angle.Simple.Its the angle between the remaining 2 H atoms in the bottom.Hope you got it. Mathematically,number of ways we can select 2 H atoms from 4. 4c2,which equals 6.
C : O are in the ratio 1 : 2
A molecule or atom that is not bonded to C or H.
The Lewis dot structure for CH3OH starts with a central C atom. Three H atoms are single bonded to the carbon atom, and an OH group is also bonded to the C atom with a single C-O bond.
......H ......| H - C - C=O ......|.... | ......H...O ............| ............H the oxygens both have two lone pairs on them and the rest are fine. Ignore the periods it was the only way I could make everything line up right.
C2H5 (neutral- no overall charge) is a free radical. Its Lewis dot structure will be two horizontal C atoms covalently bonded. One C atom will be single bonded to three H atoms. The other C atom will be bonded to two H atoms and have one electron unpaired.

They all contain C, O, H&The ratio H to C is fixed at 2:1
This is a structural formula, making the electron dot structure easy to draw. We begin from the left, with two H atoms attached to a C atom. This C atom is double bonded to another C atom. That second C atom has one H attached, and another single bond to another C atom. Finally, the last C atom is triple bonded to the Nitrogen.
H:C:::N:The Lewis structure for HCN, otherwise known as hydrogen cyanide, is fairly simple. Place the carbon atom in the center and triple bond it to a nitrogen atom. Then bond the carbon atom to a single hydrogen atom. The nitrogen atom will have a lone pair placed on it.
It is 1:2:1
