Why methyl group cannot be present at first carbon of the chain?

If a methyl group is on the first carbon, then you're just adding another carbon onto the longest chain. So if I have propane (3 single-bonded carbons) and I add a methyl group onto the end, I have 4 single bonded carbons in a row - which means I now have butane.

How is methyl made?
There is no such thing as a lone 'methyl'. A methyl group is a CH3 extending off an organic compounds main carbon chain. They can be created by the Sn2 reaction on iodomethane, or by the reaction of methyl lithium or MeMgCl with a carbon atom that is substituted with a leaving group
Why the structure of butane and methyl butane are different?
It differs on where the double bond is located. The number in front of the butene means what carbon number of the chain the double bond starts on. In 2 methyl 1 butene it is in between the 1 and 2 carbons and in 2 methyl 2 butene it is located between the 2 and 3 carbons on the butane chain.
What does 2-methylpentene look like?
The answer is in the name. "Pent" means there are 5 carbon atoms in a row. "Methyl" means there is another carbon with three hydrogens attached connected to one of them. "ene" means there is a carbon to carbon double bond somewhere along the chain and the fact it is not numbered also means it is on the end. The "2" means the methyl group is attached to the second carbon atom counting from the end with the double bond.
Structure of Acetic Acid?
A carboxyl group with a methyl group attached. It can thus also be considered the smallest fatty acid, having only one carbon in its hydrocarbon chain.
What introduces kinks in fatty acid chains and causes them to be unsaturated?
it is due to carbon carbon double bond that reduces the number of hydrogen present in the chain and lead to the whole polypeptide chain to kink.

What is the structure of methylethane?
methylethane in effect doesn't exist as it is just a synonym of propane methylethane would be one carbon atom (Methyl) attached to an ethane group, but the only carbon atoms in ethane are at the end of the chain therefore all the methyl part does is make the chain longer so it has three carbon atoms and is now propane.
What is the mistake in the iupac name of 2 methyl 3 propyne?
The 3 in front of the propyne means that the triple bond is between the 3rd and 4th carbon of the longest carbon chain in the molecule. However, you only have 3 carbons in a chain.
3 If Acid-catalyzed dehydration of 22-methyl-1-hexanol gave a number of isomeric alkenes including 2-methyl-2-heptene Write a step-wise mechanism for the formation of 2-methyl-2-heptene?
problem here.... can't form heptene (7 carbon chain) from hexanol (6 carbon chain) without another C-C bond being formed, this can't result from dehydration
What is the difference bw 2methyl 3chloro hexane and 3chloro 2methyl hexane?
Hexane is a 6 carbon chain. starting at one end, number the carbons 1 - 6. 2-methyl 3-chloro means that the methyl group attaches to carbon 2, and the chlorine attaches to carbon 3. 3-methyl 2-chloro would simply be the other way around. They are two unique and different compounds.
What is the structure of 3-methyl-3-butanol?
There is no such thing. It would be named 2-methyl-2-butanol (see link below)."Butan" is a continuous chain of 4 carbons. Starting from one side, the 3rd carbon will have both a methyl group (-CH3) as well as a hydroxyl group (-OH), hence "butanOL". Since the rules of naming require that the lowest numbers be used, and the methyl and hydroxyl groups are on the second carbon, the correct name is in fact: 2-methyl-2-butanol.

Why is carbon dioxide present in the air?
Carbon dioxide is present in the air because plants need carbon dioxide to make food and without carbon dioxide plants would die and eventually the rest of the food chain.
What is the structural formula of 3 - methylnonane?
It is a straight carbon chain composed of nine carbons with a methyl (-CH3) group attached to the third carbon. CH3-CH2-CHMe-CH2-CH2-CH2-CH2-CH2-CH3
An omega-3 fatty acid has its first double bond on the?
The first double bond is between the third and fourth carbons from the methyl (CH3) end of the fatty acid molecule.
Structure of Acetic Acid?
A carboxyl group with a methyl group attached. It can thus also be considered the smallest fatty acid, having only one carbon in its hydrocarbon chain.
