CH3-CH2-CH2-CH-CH2-CH3
6 5 4 3 2 1
Hence the correct name is 3-methylhexane.
What is 3-methylhexane?
A branching hydrocarbon having two enantiomers is 3-methylhexane. It is one of heptane's isomers. The chirality of the molecule makes it one of only two structural isomers of heptane with this feature, the other being 2,3-dimethylpentane. 3-methylhexane and 3-methylhexane are the enantiomers.
<h3>Rules for naming the compound ? </h3>
- Typically, a molecular molecule consists of two or more nonmetal components.
- Molecular compounds are termed by using the stem of the first element's name plus the suffix -ide, followed by the second element. The number of atoms in a molecule is specified using numerical prefixes.

Ok well whats the questions
Answer is: 25.84 milliliters of sodium metal.
Balanced chemical reaction: 2Na + 2H₂O → 2NaOH + H₂.
d(Na) = 0.97 g/mL; density of sodim.
m(NaOH) = 43.6 g; mass of sodium hydroxide.
n(NaOH) = m(NaOH) ÷ M(NaOH).
n(NaOH) = 43.6 g ÷ 40 g/mol.
n(NaOH) =1.09 mol; amount of sodium hydroxide.
From chemical reaction: n(NaOH) : n(Na) = 2 : 2 (1: 1).
n(Na) = 1.09 mol.
m(Na) = 1.09 mol · 23 g/mol.
m(Na) = 25.07 g; mass of sodium.
V(Na) = m(Na) ÷ d(Na).
V(Na) = 25.07 g ÷ 0.97 g/mL.
V(Na) = 25.84 mL.
None of the above?
(Is there any statements?)
