No. The formula is for propane, not pentane. A pentane would have five carbon atoms, and this formula shows only three.
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
2,2,3- trimethyl pentane has the structural shape. CH3-C(CH3)2-CH(CH3)-CH2-CH3 C8H18 is the condensed /reduced formula.
This molecule is called 2-MethylHexane.Additional Information:2-MethylHexane is a common solvent and is often found under the names, ethylisobutylmethane and isoheptane, as well as some other less common names.
OCTANE
What is ch3-ch2-ch2-ch2-ch2-ch3 ???? If you mean CH3-CH2-CH2-CH2-CH2-CH3 , then it is Hexane. Note the use of CAPITAL letters. NB One letter elemental symbols are ALWAYS a CAPITAL letter. It is the internationally recognised standard. So Carbon is 'C' , not 'c' Similarly Hydrogen is 'H' , not 'h'.
pentane
Pentane is C5H12 The Structure is as follows. CH3-CH2-CH2-CH2-CH3
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

CH3-CH(I)-CH2-CH2-CH2-CH3 + CH3-ONa --------> CH3-CH(O-CH3)-CH2-CH2-CH2-CH3 + NaI
Heptane is non polar molecule. This molecule has only carbon and hydrogen.E.N difference between two atoms is 0.4,it is nearly equal to zero.
OCTANE
Ch3-ch2-ch2-ch2-ch2-ch2-ch2-ch3
2-ethylpentane as it the carbon carbon atom in the pentane backbone has four different groups such as -H, -CH3, -CH2-CH3 and -CH2-CH2-CH3. The molecule is still an alkane because it does not have any double bonds and is made of just carbon and hydrogen.
This reaction is of a substitution type by a 'alkyl-radical' mechanism:Cl2 + CH3-CH2-CH2-CH3 --> CH2Cl-CH2-CH2-CH3 + HClor (a bit more in favor)Cl2 + CH3-CH2-CH2-CH3 --> CH3-CHCl-CH2-CH3 + HCl
