C-H bond has all the energy; yahoo I feel my body breaking up all the C-H bonds,  pow there goes some more. . .

CHO - carbon, hydrogen and oxygen.\nA compound that has a hydrocarbon (CHO) chain is considered to be an organic compound.

As the preceeding poster stated, "pentachloro" is not a chemical compound;  it could certainly be *part* of the name of a chemical compound, though, in which case it would simply mean that there are 5 (penta) chlorine atoms in the structure or a substructure of the molecule.  \n\nFor instance, pentachloroethane ( a toxic compopund) would have chemical formula C2 H Cl5.  Pentachlorobenzene would be C6 Cl5 H.  Pentachlorophenol (the nasty pesticide "lindane", which ) has formula C6 Cl5 OH, and so on.

Ethanal, commonly called acetaldehyde, is CH3-C(=O)H\n\nThe enol is a structural isomer in which a hydrogen is moved from a carbon alpha to the carbonyl (the carbon adjacent to the C=O) to the oxygen.  \n\nIts enol CH2=C(OH)H is ethenol.

Ph--CH=CH2 + H+ ----> Ph-CH2-CH2(+) + Ph-CH=CH2 ---> \n\nPh-CH2-CH2-CH(Ph)-CH2(+) -----> and so on.\n\nRead in the straight lines. You will get the mechanism

Ok.  Butanal is CH3 - CH2 - CH2 - CH = O.  According to naming scheme, you would have the CH being 1.  Therefore, it is \n\n\nCH3 - CH2 - C(CH3)2 - CH = O\n\nSince I cannot draw it, at the C(CH3) is supposed to signify that on the C there are 2 methyl groups attached.

In chemistry, hydrochlorides are salts resulting, or regarded as resulting, from the reaction of hydrochloric acid with an organic base (mostly amine).

The periods "." are mean to be spaces, but the colons ":" represent unbonded electron pairs. The hyphens "-" are single bonds. The equals sign "=" is a double bond. Every atom is represented by it's periodic table abbreviation.\n\n.........H...H\n..........|.....|\n...H - C - C - H\n..........|......|\n:O: = N: ..H\n\nThe Oxygen atom has 2 unbonded electron pairs. The Nitrogen atom has 1 unbonded electron pair. The Oxygen and Nitrogen atoms are bonded together with a double bond. None of the other atoms have any unbonded electrons.

pardon me, but why is this in chemistry?

A chemical formula states the ratios of elements within a compound. Molar Mass is simply the mass of a single molecule or formula unit of that compound, and an empirical formula states the smallest, simplified ratio in a compound. Think of it as a chemical formula reduced by a common factor.

An empirical formule simply states the ratio of the atoms making up the compound, but not the total number or their arrangement. This is what is determined by elemental analysis.\n\nA molecular formula shows the total number and their relation to each other in structure...much more important for organic chem than inorganic.\n\neg(1)...C3H6O is the empirical formula for acetone, CH3COCH3, but also for methyl vinyl ether,  CH3OCH=CH2...very different compounds\n\neg(2)...CH2 is empirical for many hydrocarbons, including 2-butene, CH3-CH=CH-CH3 and cyclohexane, ...CH2CH2CH2CH2CH2CH2...(this is a cyclic compound, imagine the 'tails' connected).

The H will attach to the Carbon atom which is already bonded to other hydrogen atoms, in this case, to carbon,2.  Bromine will bond to the other carbon, hence carbon,1.\n\nAns: d.
