One you're not too likely to run into--methanidylpropane.
More common are C4H10 (propane) or C4H8 (several things, usually butadiene resin)
CH2(Cl)CH2C(CH3)(CL)CH2CH3 Or C6H12Cl2
C8H18 this is condensed formula for 3-ethyl hexane but this formula has some other isomers. This particular isomer 3-ethyl hexane is CH3-CH2-CH(C2H5)-CH2-CH2-CH3.
The structural formula of 2-ethyl hexane is CH3(CH2)3CH(CH3)CH2CH3. It consists of an ethyl group (C2H5) attached to the second carbon atom of a hexane chain.
CH3C(CH3)2CH2CH(CH2CH3)CH2CH2CH2CH3 Remember, whatever is in brackets is connected to the carbon before it.
It is a hydrocarbon: Butyl group. As it has 4 carbons it has prefix "but-" and it has general formula CnH2n+1 so it is part of Alkyl group. Accurately it is butyl group: CH3-CH2-CH2-CH2- Remember it has a bond protruding out from last CH2

The structural formula of 2-ethyl hexane is CH3(CH2)3CH(CH3)CH2CH3. It consists of an ethyl group (C2H5) attached to the second carbon atom of a hexane chain.
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
CH3C(CH3)2CH2CH(CH2CH3)CH2CH2CH2CH3 Remember, whatever is in brackets is connected to the carbon before it.
C2H6O could be 1) Ethanol, CH3CH2OH 2) Dimethyl ether, CH3OCH3

Ch3-ch2-ch2-ch2-ch2-ch2-ch2-ch3
1. hexane: CH3-CH2-CH2-CH2-CH2-CH32. 3-methylpentane: CH3-CH2-CH(CH3)-CH2-CH33. 2-methylpentane: CH3-CH(CH3)-CH2-CH2-CH34. 2,2-dimethylbutane: CH3-C(CH3(CH3))-CH2-CH3
The molecule is called propane. It is a three-carbon alkane with the chemical formula C3H8.
The condensed formula for 2,3,3,4-tetramethylnonane is CH3-CH(CH3)-CH(CH3)-CH2-CH2-CH2-CH2-CH2-CH3.
