The carbon is in the middle; this is a tetrahedral shape, and there are zero lone pairs.
CH3CClCH2All this molecule is a three carbon structure with a chloride atom attached to the middle and a double bond between any carbon (doesn't matter were as it is equally rotatable).
Propyne is a linear hydrocarbon with 3 carbons and 4 hydrogens. Two of the carbons are triple bonded, the remaining carbon is single bonded to the middle carbon Starting at the single bonded end, you have three hydrogens bonded to the first carbon, which is single bonded to the middle carbon. The middle carbon is triple bonded to the last carbon. The last carbon is also bonded to a hydrogen. H ...\ H-C-C≡C-H .../ H
Yes, a molecule can be nonpolar when it contains polar covalent bonds, because think about it. if the molecule is linear in structure, and it has two equally polar bonds on either side, then the polarity will essentially cancel out, and it will become nonpolar.
The chemical formula of a compound does not indicate the structure of the molecule, such as the ways in which the atoms are bonded to one another. For example, CO2 is the chemical formula for carbon dioxide, but doesn't tell you how the atoms are bonded together. The structural formula of carbon dioxide is O=C=O. Now we can see that the carbon atom is in the middle, and the two oxygen atoms both form a double bond with the central carbon atom, and not to each other. It also shows that it is a linear molecule.
A carbon-oxygen group like this is referred to as a carbonyl group by itself. Any molecule that has one bonded into it's main chain is a ketone.
No. Isopropyl alcohol has the IUPAC name 2-propanol; propylene glycol is 1,2-propanediol.Essentially, isopropyl alcohol is propane with a hydroxyl group on the middle carbon; propylene glycol is propane with twohydroxyl groups, one on the middle carbon and one on one of the end carbons (it doesn't matter which; they're chemically equivalent).

The molecule is described that way in order to give an idea of the bond pattern. If you just wanted to count elements, you could also call it C2H4O2 which gives the same count. But it has a pattern. There is a carbon in the middle, it has a methyl group (CH3) attached to it, and an oxygen attached to it, and a hydroxyl group (OH) attached to it. It has 3 different bonds, the oxygen is a double bond and the other two are single bonds, adding up to four, which is exactly the valence of carbon, so it works perfectly.
Linear
A CO2 molecule is smaller. Amino acids have the general structure +H3N - Cα - COO- (with an R group and a H also attached to the middle (alpha) carbon). This means that amino acids are quite a bit larger than CO2 molecules.
CH2O, one carbon atom in the middle and from that 2 hydrogen atoms and one oxygen double bonded to the carbon. it is a planar molecule with angles of 108 (from one hydrogen to the other hydrogen) and 126 (from the oxygen to both hydrogen)
Methane has a chemical formula of CH4, 4 hydrogen atoms bonded to one carbon atom. They form a shape known as tetrahedral, one hydrogen is situated above the carbon, the other three are below the carbon, with an angle of 120o between each atom.
