Yes, both ch3ch2ch2ch2ch3 and ch3ch2ch2ch2ch2ch3 are miscible since they are both alkanes with similar intermolecular forces. CBr4 and H2O are immiscible because CBr4 is nonpolar while H2O is polar, resulting in different intermolecular forces that prevent them from mixing. Cl2 and H2O are immiscible because Cl2 is a nonpolar molecule while H2O is polar, leading to differences in intermolecular forces that hinder their ability to mix.
The systematic name for CH3CH2CH2CH2CH2CH3 is hexane. Hexane is a straight-chain alkane with six carbon atoms and the molecular formula C6H14. In the IUPAC nomenclature system, the prefix "hex-" denotes six carbon atoms, and the suffix "-ane" indicates that it is an alkane with single bonds between carbon atoms.
The compound you have written is pentane, a straight-chain alkane with 5 carbon atoms. It is a colorless, flammable liquid commonly used as a solvent in laboratories and as a fuel additive in gasoline.
