Smaller the atomic size get smaller as it goes across a period. This is because periods all have the same amount of valence electron shell numbers (like period 2 has 2 valance shells around the atom) but at the same exact time, the number of protons increase going down the period. This means there’s more/a stronger pull from the protons to the outer balance electrons making the valance electron layers pull inward more, but on the next layer of new balance electron shell is formed so the distance between the outer most balanced electron in the protons is wider than the previous level, but like before the gap decreases as a you go down the period. Hope this makes sense

The correct name is 3-methylhexane.
<h3>Structures : </h3>
The structure of 4-methylhexane is
CH3
|
CH3-CH2-CH2-CH-CH2-CH3
In the systematic nomenclature, the longest carbon chain is numbered so as to give the lowest number to the substituent.
CH3
|
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.
