Answer 1

Вот держи решение,надеюсь все понятно))

Answer 2

It seems like you provided chemical names for two compounds. Let's break down each of them:

1. 3-ethyl-4,4-dimethylpent-1-yne:

• "3-ethyl" indicates that there is an ethyl group (-CH2CH3) attached to the third carbon atom in the carbon chain.
• "4,4-dimethyl" means that there are two methyl groups (-CH3) attached to the fourth carbon atom, and they are also located symmetrically (i.e., both on the fourth carbon).
• "pent-1-yne" tells us that the carbon chain contains five carbon atoms (pent) and ends with a triple bond (yne) on the first carbon atom.

The structure can be represented as: CH3-C≡C-CH(CH3)-C(CH3)2-CH2-CH3

2. 2,2-dimethylhept-3-yne:

• "2,2-dimethyl" means that there are two methyl groups (-CH3) attached to the second carbon atom, and they are also located symmetrically (i.e., both on the second carbon).
• "hept-3-yne" indicates that the carbon chain contains seven carbon atoms (hept) and ends with a triple bond (yne) on the third carbon atom.

The structure can be represented as: CH3-C≡C-CH(CH3)-C(CH3)2-CH2-CH2-CH3

Please note that it is important to use proper chemical nomenclature to accurately represent chemical structures. Additionally, without specific molecular formulas, these representations are somewhat generalized, and there may be multiple isomers or structural variations that could fit these names.
